Remove the drop feedback row a little time after drag_leave

Browse Source 
Since ::drag-leave gets emitted before ::drag-drop, we can't just remove the drop feedback row
in drag-leave, as we *need* it during drag-drop.  So, we use the same trick as in testdnd.c - we
install a timeout handler in our drag-leave callback, and remove the feedback in the timeout callback.
