    Don't show right click menu if a new notification for the source is showing
    
    Showing the right click menu causes errors when ungrabbing focus in this case.
    It will soon be impossible to get to the right click menu anyway when a new
    notification is showing, because we are never going to show the summary
    and the new notification at the same time.
