If a RadComboBox is used as an ItemTemplate for a ListView or CollectionView on MacCatalyst, the application crashes every time you attempt to open the dropdown with the following exception:

System.InvalidOperationException: Event registration is overwriting existing delegate. Either just use events or your own delegate: Microsoft.Maui.Controls.Handlers.Items.ReorderableItemsViewDelegator`2[Microsoft.Maui.Controls.ReorderableItemsView,Microsoft.Maui.Controls.Handlers.Items.ReorderableItemsViewController`1[Microsoft.Maui.Controls.ReorderableItemsView]] UIKit.UIScrollView+_UIScrollViewDelegate

Programmatic item selection does not work from 6.3.0 version. It works in 6.2.0

When setting the SelectedItem programmatically, selection is not respected in the UI. 

There would be a blank space on the left side of DataGrid when the user keeps double clicking (editing) on different cells quickly.

Currently when a cell is edited, the underlying value is updated on every change, make it possible to update the underlying value when the edit is committed.

I auto select the text in cell once the cell is in edit mode and SelectionOnFocus is set to SelectAll in the RadEntry element inside the CellEditTemplate. I have a timer that updates other columns value but not the value in the editable cell. Still the selection is lost when row data changes.  

Null Reference exception is thrown when using Native embedding.

Dynamic change of the IsEnabled property of the RadDataGrid does not affect the RowDetails, leaving the UI inconsistent.

In my case, the RadDataGrid is disabled initially (IsEnabled=False). Some data is loaded in the DataGrid. At runtime I set the IsEnabled property of the DataGrid to true. I am then able to expand row details. The issue is that the view in the row details has the IsEnabled property set to false.
