Drag and Drop Behavior

[FeltMe]

Hello
I have Grid on Window, and i try to add Behavior for DragOver and Drop event's, witch will call my custom ReactiveCommand in MyViewModel.

<Grid DragDrop.AllowDrop="True">
			<i:Interaction.Behaviors>
				<ia:EventTriggerBehavior EventName="Drop">
					<ia:InvokeCommandAction Command="{Binding DropCommand}" />
				</ia:EventTriggerBehavior>
			</i:Interaction.Behaviors>
</Grid>

But i get a System.Xaml.XamlException: Cannot find an event named Drop on type Grid.
So i try to find else way to solve it, i found some DragDrop parameter and try to add command here DragDrop.Drop="DropCommand", and I see the following exception System.Xaml.XamlException: "Unable to resolve suitable regular or attached property Drop on type Avalonia.Input:Avalonia.Input.DragDrop.

Is it's a bug? Couse a Grid definitely has this event's.

And if i am do something wrong, please tell me how i can add a ReactiveCommand to Drop and DragOver events, which will called after event was invoked?
