Sample App Crashes when Searching due to Animation on Item

[michael-hawker]

Describe the bug

If you're typing in search, the Sample App can crash. This appears to be a failure due to an animation based effect on the search result items. There may also be a different similar issue as @avknaidu mentioned they can repro in the existing sample app, but we have since replaced it's animations with the new animation set from #3639.

Steps to Reproduce

• Can this be reproduced in the Sample App?

Steps to reproduce the behavior:

1. Open Sample app
2. Search for something like 'System'
3. Place mouse over an item so that it gets larger
4. Modify search (with keyboard)
5. Crash

Expected behavior

Not crash

Environment

Latest main

Additional context

FYI @Sergio0694

This is crashing in the Scale animation setup in the ItemContainer_PointerExited method of Shell.SamplePicker.cs which is initialized by the GridView SamplePickerGridView on each GridViewItem in SamplePickerGridView_ChoosingItemContainer.

System.ArgumentException
  HResult=0x80070057
