CDP-based Playwright clicks (locator.click()) do not reliably trigger
Svelte 5 onclick handlers — documented in commit 0c765d81 which fixed
13 other specs. The layout dropdown tests were missed in that pass.
Applies the same pattern: ((await locator.element()) as HTMLElement).click()
for button interactions, and native KeyboardEvent dispatch for the Escape
test (dispatched on the button so it bubbles to the parent div's onkeydown).
