    ChatView: update toplevel state when parent is set
    
    state-flags-changed will be emitted only when the state flags
    actually change, and therefore may not fire if the widget is
    mapped to a window that is already focused.
    In that case our tracking will get confused and think that
    the window is not focused, resulting in messages that are
    not properly acked.
