Hi there. Thanks for making such an awesome library. I was searching around trying to find out how to make an item draggable in Avalonia and almost gave up until I found this. I've figured out how to make a single `ListBox` item draggable. However, my `SelectionMode` is set to multiple so multiple items can be selected. When I select multiple items and then start to drag, all items except the one I started the drag action on get deselected. Is there a way to make dragging respect the existing selection of items in a `ListBox`?
I tried removing the drag & drop behavior and discovered that this issue seems to be with Avalonia specifically. If I start making a dragging motion, the selection is cleared.
I made a discussion post a few months ago asking about this. As far as I can tell, dragging multiple items in a ListBox with SelectionMode="Multiple" is not possible. I've created this issue as an enhancement request.
Is it possible that support could be added for this scenario in the future? If not, do you know of a way I could avoid this issue? I was thinking maybe there was a way to stop the ListBoxItem from getting the PointerPressedEvent until it was followed by a PointerReleasedEvent && no drag had occurred. However, I'm not quite familiar enough with Avalonia to pull it off.
