Steps to reproduce

1. Install dependencies with pnpm i
2. Start the development server with pnpm dev
3. Open http://localhost:5173 in your browser and notice the page freezing:

• Clicking through the bits-ui tabs componentdoes not work
• Clicking the link to /hello-world does not trigger client-side navigation, but does update the URL

5. Downgrade to Svelte 5.53.7 and notice that the issue is resolved. Might need to run pnpm dedupe after downgrading to ensure the correct version of Svelte is used.

Findings

It seems like bits-ui is needed to reproduce this issue, as the problem does not occur when using simple custom components or native HTML elements.

Another interesting thing is that removing or changing the line at src/routes/+page.svelte#L23 to not have the bits-ui avatar component or at src/routes/+page.svelte#L20 to not have the remote function call (or the bits-ui avatar component) seems to fix the issue

sv

To recreate this project with the same configuration:

# recreate this project
pnpm dlx [email protected] create --template minimal --types ts --add prettier eslint sveltekit-adapter="adapter:node" devtools-json --install pnpm ./svelte-5.53.8-mvce
