    overview: Connect item-drag signals to show/hide overview elements
    
    Anytime we begin dragging an app launcher, ensure the overview elements are
    showing. While searching, if an item-drag ends or is cancelled, hide the
    overview elements, but don't switch back to windows (which was the old
    behavior).
