Make a selection, then drag it and drop somewhere inside the same selection. As a result, selection will be cleared. Change this either to keep selection (seen as dropping into the same position) or to display "deny" cursor (like it happens on drop outside of the window, seen as dropping into an unacceptable area - inside the selection itself) - in any case selection will be unchanged.
