    messageTray: Use monitor geometry for dwelling
    
    In multi-monitor setups, the screen might extend below the edge of
    the monitor that holds the tray. In that case the tray is currently
    triggered from a secondary monitor, which is rather surprising;
    change the check to use the correct monitor geometry instead.
