Description
A CollectionView with IsGrouped set to True results in a wrong view rendering with duplicate groups when data is added, usually if not at the top scroll position. It crashes sometimes when data is removed. This happen on iOS and MacCatalyst. It works correctly on Android.
This may be related to issue #14978
Simulator.Screen.Recording.-.iPhone.15.Pro.-.2023-10-12.at.11.12.06.mp4
Steps to Reproduce
- Deploy the sample project on iOS Simulator or on Mac.
- Scroll a bit down the displayed list
- Click 'Add' to add items to the list and observe the rendering of duplicate groups.
- Click 'Clear' to reset the list: the app crash or display empty groups.
