Pointerdown attaches three document-level listeners. Without an explicit teardown, an unmount mid-drag (route change, view toggle, viewport drops below lg) left them attached and they kept writing to torn-down state cells. Wrap the cleanup in $effect's return, which Svelte 5 invokes on unmount. The listener-removal regression test pins this so the bug cannot come back silently.

sv
Everything you need to build a Svelte project, powered by sv.
Creating a project
If you're seeing this, you've probably already done this step. Congrats!
# create a new project in the current directory
npx sv create
# create a new project in my-app
npx sv create my-app
Developing
Once you've created a project and installed dependencies with npm install (or pnpm install or yarn), start a development server:
npm run dev
# or start the server and open the app in a new browser tab
npm run dev -- --open
Building
To create a production version of your app:
npm run build
You can preview the production build with npm run preview.
To deploy your app, you may need to install an adapter for your target environment.
