    swipeTracker: Ignore Meta key while workspace scroll gesture is in progress
    
    Workspace transition stopped midway when the Meta key
    was released while the two-finger scroll gesture was
    in progress. This commit ignores the Meta key once
    the gesture has been confirmed and is in motion.
