Summary

  • Replaces <a href="/aktivitaeten"> with <button type="button"> in NotificationDropdown.svelte — SvelteKit's capture-phase link interceptor never fires on a button, so the vitest-browser iframe stays on its session URL
  • Simplifies handleViewAll to a zero-arg function (drops e: MouseEvent and e.preventDefault())
  • Splits the single view-all test into two focused it() blocks and adds vi.clearAllMocks() to afterEach to prevent mock leakage

Motivation

The <a href onclick=e.preventDefault()> pattern is structurally broken in vitest-browser: SvelteKit's link interceptor is registered as a capture-phase document listener and fires before the component's bubble-phase handler. By the time handleViewAll called e.preventDefault(), the router had already initiated navigation, crashing the iframe and contaminating all subsequently-run test files with Cannot connect to the iframe errors. This dropped measured client-side coverage from >80% to ≈58%, blocking the CI coverage gate.

Fixes #551. Related: #545.

Test plan

  • npm run test --project=client NotificationDropdown → 14/14 pass, no iframe errors
  • npm run test → all 3110 tests pass, no Cannot connect to the iframe in output
  • npm run check → no new type errors in changed files

👨‍💻 Felix Brandt — Senior Fullstack Developer

Verdict: Approved

Clean fix. The root cause is well-understood, the solution is the simplest correct one, and the test suite tells the story clearly. A few minor things worth noting.

Blockers

None.

Suggestions

1. The ADR pattern note in docs/adr/012-browser-test-mocking-strategy.md contradicts the fix

The note added says:

When an overlay or dropdown contains a navigation link (<a href="…">), use e.preventDefault() + goto(path) in the click handler instead of letting the browser follow the href. The href attribute should still be present for right-click / open-in-new-tab semantics.

But this PR deliberately removes the href and replaces the <a> with a <button>. The documented pattern (<a href> + e.preventDefault()) is exactly the broken pattern this PR fixes. The note should describe the <button onclick={goto(…)}> pattern that was actually shipped, not the pattern that was removed.

2. handleViewAll order: onClose() before goto() — is that intentional?

Calling onClose() first then goto() means the dropdown closes before navigation happens. That's probably correct (avoids a visible stale dropdown during the transition), but given the PR description specifically mentions the SvelteKit capture-phase router issue, a one-line comment explaining the ordering would make future reviewers confident this isn't accidental.

3. Missing aria-label for the "view all activities" button — nice to have

The button renders the i18n string m.chronik_view_all() as its label, so it's technically accessible. No issue here. Just noting that the button has no explicit aria-label but doesn't need one since it has visible text content.

4. Test isolation improvement: afterEach cleanup ordering

afterEach(() => {
    cleanup();
    vi.clearAllMocks();
});

vi.clearAllMocks() after cleanup() is fine — mocks are independent of the DOM. No action needed, just confirming this is correct.

5. page.getByRole('button', { name: /alle aktivitäten|view all/i }) — good pattern

Using a regex that matches both German and English i18n output means this test won't break when the locale changes in CI. Good defensive choice.

🏛️ Markus Keller — Senior Application Architect

Verdict: ⚠️ Approved with concerns

The fix is architecturally sound — it correctly resolves the interaction between SvelteKit's capture-phase router and the vitest-browser iframe, and the new pattern (<button> + programmatic goto()) is the right approach. My concern is with the documentation layer, which is partially contradictory.

Blockers

ADR-012 pattern note is incorrect and will cause future harm

docs/adr/012-browser-test-mocking-strategy.md now contains:

When an overlay or dropdown contains a navigation link (<a href="…">), use e.preventDefault() + goto(path) in the click handler instead of letting the browser follow the href. The href attribute should still be present for right-click / open-in-new-tab semantics.

This is the opposite of what was actually implemented. The PR removes the <a href> element entirely and replaces it with a <button>. A future developer reading this ADR note will re-introduce the broken <a href> + e.preventDefault() pattern in good faith, causing a repeat of issue #551.

The note should document the <button type="button" onclick={handleViewAll}> pattern and explain why <a href> is problematic in vitest-browser contexts. The "right-click / open-in-new-tab" rationale in the note is also now moot since there is no href.

This must be corrected before merge — ADRs are the codebase's institutional memory. A wrong ADR is worse than no ADR.

Suggestions

Layering is cleangoto() is called from the component, not from a server load function. This is the right layer for a UI-driven navigation action from a dropdown.

Module boundary is respectedNotificationDropdown receives onClose as a prop and calls goto() from $app/navigation. No reach into another domain's internals. Good.

CSS architecture improvement is welcome — Moving chronik-fade-in and the print styles to layout.css is the right architectural decision. Component-scoped CSS that contains @keyframes generates Tailwind noise and doesn't benefit from scoping. Global animations belong in the global stylesheet.

Documentation table check — This PR changes no routes, no backend packages, no DB schema, and no new ErrorCode/Permission values. The doc table in my review guidelines has no required updates for this change. ✓

🔒 Nora "NullX" Steiner — Application Security Engineer

Verdict: Approved

No security regressions introduced. I checked the relevant attack surfaces for this change.

What I checked

1. Open redirect / navigation injection

goto('/aktivitaeten') uses a hardcoded string literal — no user-controlled input flows into the navigation target. No open redirect risk.

2. XSS via button content

The button renders {m.chronik_view_all()} — a Paraglide i18n function call whose output is controlled by the project's message catalog, not user input. Svelte's template compiler escapes text node interpolations. No XSS vector here.

3. Loss of href attribute — security implications

The original <a href="/aktivitaeten"> carried CSRF-neutral semantics (a GET navigation). Replacing it with <button> + goto() is an equivalent or safer pattern from a security perspective — no href means no URL that could be modified via DOM injection, bookmarked to a crafted path, or followed without JS.

The ADR note's suggestion to "keep the href for right-click semantics" would actually reintroduce a small attack surface (an anchor with a navigable href that JS then intercepts). The pure <button> approach is cleaner from a security standpoint.

4. Mock leakage between tests

vi.clearAllMocks() in afterEach correctly prevents goto mock state from bleeding into subsequent tests. Without this, a failing assertion in test N could affect test N+1's mock call counts. Good defensive test hygiene.

5. $app/navigation import scope

goto is imported from SvelteKit's $app/navigation module, which is a framework-internal alias resolved at build time. No external module resolution attack surface.

Summary

Clean change from a security perspective. The move away from <a href> + e.preventDefault() toward <button> + goto() marginally reduces the attack surface. The test isolation improvement via vi.clearAllMocks() is good practice.

🧪 Sara Holt — Senior QA Engineer

Verdict: Approved

The test changes are high quality. The split into two focused it() blocks, the mock isolation via vi.clearAllMocks(), and the switch from getByRole('link') to getByRole('button', { name: ... }) are all correct improvements. Let me go through my full checklist.

What I checked

Test naming — ✓

  • 'calls onClose when the view-all button is clicked' — sentence-style, describes behavior
  • 'navigates to /aktivitaeten when the view-all button is clicked' — explicit about the expected route

Both names are self-documenting. When CI fails, no one needs to read the test body to understand what broke.

One logical assertion per test — ✓

Previously a single test asserted both onClose and implicitly the link behavior. Now they're split: one test owns onClose, the other owns goto. Clean.

Test isolation — ✓

vi.clearAllMocks() in afterEach prevents mock call counts from the goto mock leaking into subsequent tests. This is the correct fix for cross-test contamination.

Selector specificity — ✓

getByRole('button', { name: /alle aktivitäten|view all/i }) is role-based and locale-resilient. Prefer this over text-only selectors.

Coverage of the regression — ✓

The new test 'navigates to /aktivitaeten when the view-all button is clicked' directly verifies the behavior that was broken (iframe navigation crash). The underlying crash isn't testable in a unit test, but the mock assertion on goto confirms the correct handler fires.

Suggestions

Missing: test for ordering of onClose() + goto()

handleViewAll() calls onClose() first, then goto(). There are two separate tests but neither verifies the ordering of these two calls. If someone accidentally swaps the order, both existing tests still pass. This is a minor concern (the ordering matters for UX — close before navigate), but a combined assertion or vi.fn() call order check could catch it:

it('calls onClose before navigating', async () => {
    const callOrder: string[] = [];
    const onClose = vi.fn(() => callOrder.push('close'));
    (goto as ReturnType<typeof vi.fn>).mockImplementation(() => callOrder.push('goto'));
    // render + click ...
    expect(callOrder).toEqual(['close', 'goto']);
});

This is a "nice to have" — not a blocker for this PR.

Coverage gate impact

The PR description states this fix restores coverage from ~58% back to >80% by preventing the iframe crash from dropping subsequent test files' coverage. That's a meaningful CI reliability improvement and the right motivation for this fix.

🎨 Leonie Voss — UI/UX Design Lead & Accessibility Strategist

Verdict: ⚠️ Approved with concerns

The semantic change from <a> to <button> has accessibility implications that need attention. The fix is correct from a testing perspective, but introduces a UX regression for keyboard and AT users.

Blockers

1. <button> without touch target sizing — WCAG 2.2 §2.5.8

The "view all" element renders as:

<button
    type="button"
    onclick={handleViewAll}
    class="text-xs font-medium text-ink-2 transition-colors hover:text-ink"
>
    {m.chronik_view_all()}
</button>

There is no minimum height/width applied. A bare <button> with only text and no padding/size constraint will render at its natural text height — typically 18–20px tall. WCAG 2.2 Success Criterion 2.5.8 (Target Size, Minimum) requires 24×24px. Our design standard for this audience (60+) is 44×48px. The previous <a> element had the same issue, so this isn't a regression introduced here, but it's worth flagging since we're touching this element.

Suggested fix:

<button
    type="button"
    onclick={handleViewAll}
    class="text-xs font-medium text-ink-2 transition-colors hover:text-ink min-h-[44px] px-1"
>

2. <button> announces as "button" to screen readers — <a> announced as "link"

Screen readers differentiate between links (navigate somewhere) and buttons (trigger an action). This element navigates to /aktivitaeten, which semantically makes it a link. By changing to <button>, screen readers will announce "alle Aktivitäten, button" instead of "alle Aktivitäten, link". A user navigating by landmark or role will not find it in the links list.

The production UX fix would be to use a visually-styled anchor that calls goto() programmatically — but that's the pattern that breaks in vitest-browser. This is a genuine tension between test infrastructure constraints and semantic correctness.

Pragmatic resolution: Accept the <button> for now, add role="link" to restore screen reader semantics:

<button
    type="button"
    role="link"
    onclick={handleViewAll}
    class="..."
>

This is unusual but valid HTML — role="link" on a <button> overrides the implicit button role. Note that this won't give keyboard users the Enter key navigation affordance (buttons use Space + Enter; links use only Enter) but VoiceOver/NVDA will announce it as a link.

Suggestions

prefers-reduced-motion for chronik-fade-in — ✓ already handled

The @media (prefers-reduced-motion: reduce) block correctly disables the animation. This is the right implementation — no action needed.

Print styles in layout.css — ✓ correct location

Moving :global(.app-nav) { display: none } and @page { margin: 1.5cm } to the global stylesheet is the right call. Scoped component styles cannot reliably target global print context.

Animation name namespacing — ✓

Renaming .fade-in.chronik-fade-in and the keyframe accordingly is good hygiene. The generic .fade-in name risked collisions with other components that might define their own fade animations in the global scope.

⚙️ Tobias Wendt — DevOps & Platform Engineer

Verdict: Approved

No infrastructure, CI, or deployment changes in this PR. From a platform perspective this is clean.

What I checked

No Docker Compose changes — no new services, no exposed ports, no volume changes.

No CI workflow changes — the fix targets the test runner (vitest-browser iframe crash), but the CI workflow files themselves are unchanged. The fix should naturally restore the coverage gate without any pipeline modifications.

No new environment variables$app/navigation is a SvelteKit build-time alias, not a runtime env var. No .env changes needed.

No new infrastructure dependenciesgoto from $app/navigation is part of SvelteKit's existing bundle. No new npm packages added.

Observation

The PR description mentions that the iframe crash dropped measured coverage from >80% to ≈58%, which was blocking the CI coverage gate. That means this fix restores CI green without touching the coverage threshold or CI configuration — exactly the right approach. The right fix is "make the code not crash the iframe", not "lower the threshold to 58%".

LGTM from infrastructure side.

📋 Elicit — Requirements Engineer

Verdict: Approved

Reviewing from a requirements completeness and acceptance criteria perspective.

Requirements traceability

The PR references issue #551 (fixed) and issue #545 (related). The PR description includes a test plan with three specific, verifiable acceptance criteria:

  • npm run test --project=client NotificationDropdown → 14/14 pass, no iframe errors
  • npm run test → all 3110 tests pass, no Cannot connect to the iframe in output
  • npm run check → no new type errors in changed files

These are testable, binary, and specific. Good requirements hygiene.

Scope assessment

The PR description clearly states what changed and why. The motivation section correctly identifies the root cause (SvelteKit's capture-phase link interceptor firing before the bubble-phase handler). No scope creep detected — the change is bounded to:

  1. The broken element in NotificationDropdown.svelte
  2. The test file covering it
  3. CSS extraction for two unrelated Tailwind noise issues
  4. Documentation of the pattern in ADR-012

Gap: ADR-012 documents the wrong pattern

The pattern note added to the ADR describes <a href> + e.preventDefault() + goto(), which is the broken pattern this PR removes, not the implemented solution. From a requirements perspective, this is a documentation defect: the ADR will mislead future implementers and produce requirements drift.

The implemented behavior is:

  • Element: <button type="button">
  • Handler: onclick={handleViewAll} where handleViewAll calls onClose() then goto('/aktivitaeten')
  • Rationale: avoids SvelteKit's capture-phase link interceptor entirely

The ADR note should document this pattern, not the discarded alternative.

Acceptance criteria coverage

The test plan covers the happy path (test pass/fail counts) and type safety. It does not explicitly cover the accessibility regression (screen readers announcing button vs link), but that is outside the scope of this bug fix PR. Tracking that as a separate issue would be appropriate.

It does not explicitly cover the accessibility regression (screen readers announcing `button` vs `link`), but that is outside the scope of this bug fix PR. Tracking that as a separate issue would be appropriate.

Review concerns addressed

Three blockers and two suggestions resolved in two new commits:

9e8bb0addocs(adr-012): correct pattern note to document button+goto, not anchor+preventDefault

Addresses: Markus (blocker), Felix (suggestion 1), Elicit (gap)

The pattern note in docs/adr/012-browser-test-mocking-strategy.md previously documented the broken <a href="…"> + e.preventDefault() approach (the exact pattern this PR removes). Replaced it with the correct description: use <button type="button"> + goto(path), and explains why the anchor fails — SvelteKit's capture-phase link interceptor fires before the bubble-phase onclick, making e.preventDefault() too late.

Addresses: Leonie (blockers 1 + 2), Felix (suggestion 2), Sara (suggestion)

  • role="link" on the view-all button — overrides the implicit button role so VoiceOver/NVDA announces it as "alle Aktivitäten, link" rather than "button". Resolves Leonie's screen reader semantics concern.
  • min-h-[44px] px-1 added to the button class — meets WCAG 2.2 §2.5.8 (24×24px minimum) and our 44×48px design standard for the 60+ audience. Resolves Leonie's touch target concern.
  • Call-order comment in handleViewAll: onClose(); // close first — avoids stale dropdown during navigation transition. Resolves Felix's ordering question — the sequence is intentional, not accidental.
  • Call-order test added: 'calls onClose before navigating to /aktivitaeten' — asserts callOrder === ['close', 'goto'] using Sara's exact suggested pattern. Test selectors updated from getByRole('button', …) to getByRole('link', …) to match the new role.

Verification

  • NotificationDropdown spec: 15/15 pass (was 14 — +1 call-order test), no iframe errors
  • Full suite: 3111/3111 pass
  • npm run check: no new errors in changed files

What I Checked

Documentation currency — my primary concern for every PR. Let me run through the checklist:

Change in this PR Doc update required? Status
No Flyway migrations db-orm.puml / db-relationships.puml N/A
No new backend packages CLAUDE.md package table N/A
No new SvelteKit routes CLAUDE.md route table N/A
No new Docker service docker-compose / DEPLOYMENT.md N/A
Architectural decision with lasting consequences New ADR entry Done — docs/adr/012-browser-test-mocking-strategy.md updated with the button+goto pattern note

The ADR update is exactly right. The root cause here — SvelteKit's capture-phase link interceptor firing before the component's bubble-phase handler — is subtle enough that future developers would repeat this mistake without the documented pattern. The note is precise and references the canonical example.

Architecture Observations

Moving styles to layout.css is correct. The chronik-fade-in animation and print styles were leaking into component-scoped <style> blocks. Centralising them in layout.css is the right boundary: shared animations belong at the global layer, not scattered in components that happen to use them first.

The button + goto() pattern is a clean workaround for the iframe interception constraint. There is no architectural alternative given the SvelteKit capture-phase constraint. The pattern is documented, the fix is minimal, and it avoids SvelteKit internals.

No Blockers

No module boundary violations, no new coupling, no missing documentation. This is a well-scoped fix.

👨‍💻 Felix Brandt — Senior Fullstack Developer

Verdict: ⚠️ Approved with concerns

Blockers

None.

Suggestions

1. Prefer vi.mocked() over the type cast in the call-order test

In NotificationDropdown.svelte.test.ts (line ~198):

// Current — verbose cast, non-obvious pattern
(goto as ReturnType<typeof vi.fn>).mockImplementation(() => callOrder.push('goto'));

// Cleaner — Vitest's built-in typed wrapper
vi.mocked(goto).mockImplementation(() => callOrder.push('goto'));

vi.mocked() exists precisely for this. It returns the mock with the correct type without a manual cast, which reads better and is the idiomatic Vitest pattern.

What Looks Good

  • handleViewAll() is clean: zero-arg, two lines, does one thing. Exactly right size.
  • The "why" comment in handleViewAll (// close first — avoids stale dropdown during navigation transition) is a legitimate why-comment: it explains a non-obvious ordering constraint. Good call including it.
  • vi.clearAllMocks() in afterEach: correctly prevents mock leakage across tests. This is the fix that matters for test isolation.
  • The call-order test (expects callOrder to equal ['close', 'goto']) is a precise, behavior-level assertion for a subtle ordering invariant. This is the kind of test that actually catches regressions.
  • CSS consolidation: removing the scoped <style> blocks from ChronikFuerDichBox.svelte and hilfe/transkription/+page.svelte in favour of layout.css is correct. .chronik-fade-in is now namespaced (no collision risk) and the @media print rule belongs at the global layer.

🔒 Nora "NullX" Steiner — Application Security Engineer

Verdict: Approved

What I Checked

This is a frontend-only component fix with no backend changes, no auth flow changes, and no new API surface. My scan was focused on:

  1. Navigation injection riskgoto('/aktivitaeten') uses a hardcoded string literal. No user-controlled input reaches goto(). Zero injection risk.

  2. role="link" on a button — not a security issue. The element's semantics change for AT, but no security boundary is affected.

  3. Mock setup in testsvi.mock('$app/navigation', () => ({ goto: vi.fn() })) is a proper module boundary mock. It does not expose any real navigation or auth state.

  4. No new endpoints, no new permissions, no new cross-origin concerns.

  5. No innerHTML, eval(), or dangerouslySetInnerHTML patterns introduced.

Nothing to Flag

Clean from a security perspective. The fix actually removes a click handler from an anchor element (the previous onclick={onClose} pattern), which slightly reduces the attack surface for clickjacking-style confusion — though that wasn't the intent here.

🧪 Sara Holt — QA Engineer & Test Automation Specialist

Verdict: ⚠️ Approved with concerns

What Looks Good

  • vi.clearAllMocks() in afterEach — this is the fix that actually prevents the mock leakage. Combined with cleanup(), the afterEach hook is now correct and deterministic.
  • Test split into focused it() blocks — each test has one reason to fail. The original single test was doing two things (asserting onClose called AND asserting navigation). The split is correct per Arrange-Act-Assert discipline.
  • Call-order test — asserting callOrder === ['close', 'goto'] is a precise behavioral assertion for a subtle invariant. This is the right way to test ordering contracts.
  • getByRole('link', { name: /alle aktivitäten|view all/i }) — correctly queries by the element's ARIA role (role="link" on the button), not by CSS class or position. Resilient to markup changes.

Concerns

1. The navigation test re-renders with a fresh onClose: () => {} but the order test uses a spy onClose

These are separate renders in separate it() blocks — which is correct isolation. But the navigation test doesn't verify that onClose was NOT called (it was given a stub that doesn't assert). This is fine — the concerns are separated across tests. Actually no concern here, just noting the design is intentional.

2. vi.mocked(goto) is cleaner than the cast in the order test

// Current
(goto as ReturnType<typeof vi.fn>).mockImplementation(() => callOrder.push('goto'));

// Idiomatic
vi.mocked(goto).mockImplementation(() => callOrder.push('goto'));

This is a suggestion, not a blocker. The current cast works but vi.mocked() is the canonical Vitest pattern for typing already-mocked imports.

3. No test for the "does NOT navigate when only marking as read" path

The PR adds tests for the view-all button. But there's no negative assertion test: "clicking a mark-read button does NOT call goto." This would prevent future regressions where goto is accidentally called in a different handler. Low priority since the mock is cleared between tests, but worth noting.

Coverage Assessment

The original coverage gate blockage (≈58% vs >80%) was caused by iframe crashes contaminating subsequent test files. The fix addresses the root cause rather than adding compensating tests — which is the right call. The new tests are genuinely additive.

🎨 Leonie Voss — UI/UX Design Lead & Accessibility Strategist

Verdict: ⚠️ Approved with concerns

Blockers

None that prevent merge, but one concern needs attention before the next sprint.

Concerns

1. role="link" on a <button> — keyboard contract mismatch (Medium severity)

<button
    type="button"
    role="link"
    onclick={handleViewAll}
    class="min-h-[44px] px-1 text-xs font-medium text-ink-2 transition-colors hover:text-ink"
>

The intent is correct — telling AT this element navigates like a link. But there's a subtle keyboard contract issue:

  • ARIA spec says role="link" elements are activated by Enter only (not Space)
  • A native <button> responds to both Enter AND Space
  • Result: pressing Space activates the button even though role="link" tells screen reader users "this is a link, Space does nothing"

For keyboard-only users and screen reader users, this creates an inconsistency: Space works, but their AT told them it shouldn't. WCAG 4.1.2 (Name, Role, Value) requires the role to accurately represent the accessible behavior.

Recommended fix — two options:

Option A: Remove role="link" and style the button to look like a link. The button will be announced as "button" (accurate), and screen readers will say "press Space or Enter to activate":

<button
    type="button"
    onclick={handleViewAll}
    class="min-h-[44px] px-1 text-xs font-medium text-ink-2 transition-colors hover:text-ink focus-visible:ring-2 focus-visible:ring-brand-navy focus-visible:ring-offset-1 rounded-sm"
>

Option B: Keep role="link" and suppress Space activation explicitly:

onkeydown={(e) => { if (e.key === ' ') e.preventDefault(); }}

Option A is simpler and more semantically honest.

2. No explicit focus-visible ring on the new button (Minor)

The previous <a> presumably inherited project-wide anchor focus styles. The new <button> does not have an explicit focus-visible:ring-* class in the diff. The Tailwind base reset may strip browser defaults. Verify this renders a visible focus indicator, especially at high contrast mode.

Suggested addition: focus-visible:ring-2 focus-visible:ring-brand-navy focus-visible:ring-offset-1 rounded-sm

What Looks Good

  • min-h-[44px] — correct 44px touch target on the button. This is a WCAG 2.2 requirement and important for the 60+ audience.
  • Typography preservedtext-xs font-medium text-ink-2 hover:text-ink matches the previous anchor appearance. The visual change is invisible to sighted users.
  • chronik-fade-in in layout.css with @media (prefers-reduced-motion: reduce) — the reduced-motion media query is correctly preserved in the migration to layout.css.

📋 Elicit — Requirements Engineer

Verdict: Approved

Requirements Traceability Check

The PR description is well-structured. Let me verify alignment between stated motivation, implementation, and acceptance criteria:

Root cause claim: SvelteKit's capture-phase link interceptor fires before the component's bubble-phase onclick, making e.preventDefault() arrive too late.

Implementation response: Replace <a href> with <button type="button">. A button carries no href, so the capture-phase interceptor never fires. This is a causal fix, not a workaround.

Acceptance criteria:

  • NotificationDropdown → 14/14 pass, no iframe errors — directly verifiable
  • Full suite → 3110 pass, no Cannot connect to the iframe — verifiable
  • npm run check → no new type errors — verifiable

All three criteria are measurable and test-executable.

Scope Assessment

The PR fixes one root cause and delivers three incidental improvements (CSS consolidation, test isolation via vi.clearAllMocks(), ADR documentation). None of the incidental changes introduce new requirements or expand scope. The CSS moves are refactors, not feature changes.

Open Requirements Question

The PR references both #551 (the iframe crash bug) and #545 (the broader notification dropdown fix). It's clear this closes #551. The relationship to #545 should be confirmed — if #545 is the parent issue, this PR should be noted as one of potentially multiple contributions to that issue, so the acceptance criteria of #545 are tracked separately.

No blockers from a requirements perspective.

Verdict: Approved

What I Checked

This PR touches only frontend Svelte components, test files, a CSS file, and an ADR doc. No changes to:

  • docker-compose.yml or any Compose overlay
  • CI workflow files (.gitea/workflows/)
  • backend/ code, no new JARs or services
  • Environment variables, secrets, or volume mounts
  • Caddy configuration or reverse proxy rules

Nothing in my domain is affected. The fix is entirely contained to the frontend test layer and component markup.

One Observation (Non-blocking)

The root cause (SvelteKit's capture-phase link interceptor crashing the Playwright iframe) is a CI environment concern. The fix addresses it correctly at the component level, which is better than fighting it at the CI/Playwright configuration level. Good call — infrastructure workarounds for application-layer problems are always more fragile than fixing the application layer.

LGTM from an infrastructure perspective.

SvelteKit's capture-phase link interceptor fires before the component's
onclick handler, so e.preventDefault() was structurally too late to stop
iframe navigation in vitest-browser. Replacing the <a href> with a
<button type="button"> removes the href entirely — the interceptor never
fires — and the existing goto() mock in tests is sufficient.

Also splits the single view-all test into two focused it() blocks and
clears mocks in afterEach to prevent cross-test mock leakage.

Fixes #551

The role=link override on a <button> creates a WCAG 4.1.2 keyboard-contract
mismatch: ARIA role=link tells AT users "press Enter to activate (Space does
nothing)", but the native <button> responds to both Enter and Space. Removes
the override so the element is announced as "button" (accurate).

Test selectors updated from getByRole('link') to getByRole('button')
accordingly.

Round-2 concerns addressed

Two new commits:

6b785579refactor(notification-tests): use vi.mocked instead of type cast in call-order test

Addresses: @Felix (suggestion 1), @Sara (suggestion 2)

Replaces (goto as ReturnType<typeof vi.fn>).mockImplementation(...) with vi.mocked(goto).mockImplementation(...) in the call-order test. vi.mocked() is the idiomatic Vitest pattern — no manual type cast needed.

Addresses: @Leonie (concern 1)

role="link" on a <button> creates a WCAG 4.1.2 keyboard-contract mismatch: ARIA role="link" tells AT users "press Enter to activate (Space does nothing)", but the native <button> responds to both Enter AND Space. Leonie's Option A applied — remove role="link" so the element is announced as "button" (semantically accurate). Test selector queries updated from getByRole('link', ...) to getByRole('button', ...) accordingly; test descriptions updated to match.

@Leonie concern 2 (focus-visible ring — minor): No code change needed. layout.css line 424 has a global fallback :focus-visible { outline: 2px solid var(--c-focus-ring); } that applies to all interactive elements. The button already renders a visible keyboard focus indicator.

Verification

  • NotificationDropdown spec: 15/15 pass, no iframe errors
  • Full suite: 3112/3112 pass
  • npm run check: no new errors in changed files
## Round-2 concerns addressed Two new commits: ### `6b785579` — `refactor(notification-tests): use vi.mocked instead of type cast in call-order test` Addresses: **@Felix (suggestion 1)**, **@Sara (suggestion 2)** Replaces `(goto as ReturnType<typeof vi.fn>).mockImplementation(...)` with `vi.mocked(goto).mockImplementation(...)` in the call-order test. `vi.mocked()` is the idiomatic Vitest pattern — no manual type cast needed. ### `89860403` — `fix(notification): remove role=link from view-all button — restores semantically honest button role` Addresses: **@Leonie (concern 1)** `role="link"` on a `<button>` creates a WCAG 4.1.2 keyboard-contract mismatch: ARIA `role="link"` tells AT users "press Enter to activate (Space does nothing)", but the native `<button>` responds to both Enter AND Space. Leonie's Option A applied — remove `role="link"` so the element is announced as "button" (semantically accurate). Test selector queries updated from `getByRole('link', ...)` to `getByRole('button', ...)` accordingly; test descriptions updated to match. **@Leonie concern 2 (focus-visible ring — minor):** No code change needed. `layout.css` line 424 has a global fallback `:focus-visible { outline: 2px solid var(--c-focus-ring); }` that applies to all interactive elements. The button already renders a visible keyboard focus indicator. ### Verification - `NotificationDropdown` spec: **15/15 pass**, no iframe errors - Full suite: **3112/3112 pass** - `npm run check`: no new errors in changed files
