    W32: Don't unregister parent window of an embedded widget
    
    This leads to an assertion failure, because parent window is never registered
    in the first place, widget's own GdkWindow is. But that window is unregistered
    in a generic fashion by GtkWidget code, so there's nothing for us to do here.
