Describe the bug

After performing an AI powered search on the docs site, and dismissing the search dialog, the site locks up and the browser enters a frozen state.

Steps to Reproduce the Bug

1. Open search
2. Perform an AI search on a query
3. Dismiss the search dialog

The issue occurs reliably, on every search attempt. It occurs if you dismiss the dialog while the AI is generating, and also if you wait for the AI to fully complete before dismissing it.

Expected behavior

Normal site functionality after performing a search

Drag and drop is broken with firefox + wayland in arch linux, so I can't upload the file at the moment. Here's a link to the video uploaded to the TanStack Discord server

Additional context

No response

Start at https://tanstack.com/router/latest and reproduce the freeze by running an AI search, then dismissing the dialog both during and after generation. Trace the docs site's search dialog dismissal path in the frontend and verify that normal site functionality remains responsive after either flow.
