    Remove a shortcut in gtk_widget_set_focus_child
    
    Since focus can now be represented by more than one state,
    just looking at the focus_child is no longer sufficient - we
    may fail to propagate :focus(visible) if we do so. For now,
    just remove the shortcut and always do the work.
