Describe the bug

Using a GridView with the ItemsSource set to a class derived from ObservableCollection<Item> causes a crash when items are reordered due to an InvalidCastException. A workaround it to add code according to the documentation (https://github.com/manodasanW/WinUI-Gallery/blob/16ed717700b929dcb6591d32a4f10cd8b102aa07/WinUIGallery/VtableInitialization.cs#L24-L53) with typeName set to System.Collections.Specialized.SingleItemReadOnlyList.

Expected behavior

Should work without additional code
