    window: Remove needless call to ensure_state_flag_backdrop() on map
    
    This call was forcing needless work since gtk_window_map() already
    does a gdk_window_show() which initially sets GDK_WINDOW_STATE_FOCUSED
    that we then handle regularly on the widget's window state event
    handler.
