useQueries() causes infinite rerenders since @tanstack/[email protected] #9638

Describe the bug

We've noticed a bug in useQueries() that was introduced in version 5.85.9.

Dynamically updating the list of queries passed to useQueries() causes an infinite rerender, but curiously only if the last element of the list is removed.

Minimal Codesandbox examples:

• 5.85.8 (still working)
• 5.85.9 (broken)

It is still broken in the latest version. We suspect this change to be the culprit.

Your minimal, reproducible example

https://codesandbox.io/p/devbox/8ffffc?file=%2Fsrc%2FApp.tsx

Steps to reproduce

1. Open Devtools
2. Click on "Remove id2"
3. Check render count

When removing id1, no infinite rerenders occur.

Expected behavior

No infinite rerenders when updating the list passed to useQueries()
