Tanstack Virtual freezes when using React DevTools

[Firnu]

Describe the bug

Tanstack Virtual with WindowVirtualizer freezes when selecting any child of the virtualized list in the Components tab of React Devtools. Only full page refresh restores the virtualizer. The issue starts with a warning in the console: Could not find Fiber with id "2689".

Virtualization implementation can be found here:
https://github.com/Firnu/calamariassignment/blob/main/src/pages/doctors/%40components/DoctorsList.tsx

From my tests, the issue persists in other implementations as well.

Steps to reproduce

1. Open the provided example (make sure to have React Devtools installed).
2. Open Chrome dev tools F12
3. Scroll the list to confirm that Tanstack Virtual is working
4. Select any item in React Devtools (Components tab) that is a child of the virtualizer.
5. Scroll the list again, the items will get frozen (only last displayed items will stay visible). The console should print a warning Could not find Fiber with id "x"

Please refer to the attached video.

Expected behavior

Tanstack Virtual should continue working even when selecting items in React Devtools (Components tab). Worst case scenario, it should be able to restore itself when items related to virtualizer are deselected.

The same thing happens in Chrome DevTools "Elements" as well as React DevTools (but no console warnings are shown).
It did not happen in Safari DevTools.
