    clutter: Drop unpaired special handling of LEAVE event on stage
    
    This is just "necessary" for --nested stages, since the pointer is
    allowed to leave the stage in that case. Since the only side effect
    is that there is still a pointer focus somewhere inside the stage,
    simply drop this.
    
    This is a small leftover of commit b8f92a6ce4966, since we stopped
    handling the double ENTER event there.
