Inline Rename breaks when deleting portion of identifier

[DustinCampbell]

Version Used: Latest IntPreview

Steps to Reproduce:

1. Create a long identifier.

   int IdentifierLotsOfWords = 42;

2. Select a portion of the identifier.
   

3. Press F2 to start an Inline Rename
   

4. Press the DELETE key to delete the selected portion.

Expected Behavior: The selected portion of the identifier is deleted.

Actual Behavior: The rename is cancelled.

Note: Repeating steps 2-4 will eventually get Inline Rename in a bad state where the UI won't go away and there's a gold bar that reports a COMException. Here's the ActivityLog from session where this happened: ActivityLog.txt

Does this reproduce is you manually put focus into the flyout? I have a feeling this is a case where focus should have been in the flyout and isn't. Likely fixed by #60846

Wasn't able to repro this on latest builds. We demonstrate the expected behavior
