SfBottomSheet.IsOpenProperty Binding Does Not Behave as Expected

CommunityToolkit.Maui Version="10.0.0"
CommunityToolkit.Maui.Markup Version="5.1.0"

The SfBottomSheet component's IsOpenProperty is bound to the SelectedDevice property using a converter. While it works as expected initially, it fails to update when SelectedDevice is reset to null.

• Initial Behavior: When SelectedDevice is null and IsOpen property is false, the bottom sheet remains closed as expected.
• Expected Behavior on Selection: When a device is selected, SelectedDevice is assigned a non-null value. The converter updates IsOpen property to true, and the bottom sheet opens as expected.
• Unexpected Behavior on Reset: When SelectedDevice is reset to null, the converter updated IsOpen property to false. However, the bottom sheet remains open.

var bottomSheet = new SfBottomSheet
{
    Content = CreateMainContent(),
    BottomSheetContent = CreateBottomSheetContent()
}.Bind(SfBottomSheet.IsOpenProperty, 
       static (ViewModel vm) => vm.SelectedDevice,
       convert: device => device is not null);

Have you found a workaround?

Instead of relying on data binding, using an event-based approach resolves the issue and ensures the IsOpen property updates as expected when SelectedDevice is reset to null.

        viewModel.PropertyChanged += (sender, args) =>
        {
           if (args.PropertyName == nameof(viewModel.SelectedDevice))
          {
          		bottomSheet.IsOpen = viewModel.SelectedDevice != null;
          }
        };
