For any bugfix PR, you'll need to add a test for the fixed behavior in pandas/tests/

Thanks @pradeepb2505, besides adding the test, you'll have to run the two missing points in the checklist in the description. Thanks!

Sorry @pradeepb2505, this was fixed by #27664.

Let us know if you want help finding another issue to work on.
