    widget: Treat key controllers like gestures
    
    For the purposes of cutting short event handling,
    treat key controllers like gestures. It is fairly
    common to have multiple key controllers on a widget,
    and the event handling can inadvertently cut short
    e.g. by modifier key releases that return TRUE
    from handle_event.
