    workspace: Reset idle hide timeout for overlays on reentry
    
    Instead of returning and waiting until the old timeout is finished,
    start a new idle hide timeout for the overlay when the pointer enters a
    window clone. This makes sure the timeout for hiding the overlay after
    the pointer left the clone mostly stays the same (except when leaving
    the clone via the title or the close button).
