    scrolledwindow: Ensure the animation is cancelled on arriving scroll events
    
    When the scrolledwindow receives scroll events, it ensures the timeout to
    maybe start the "snap back to edges" animation is reset, but it does nothing
    about the animation source. It must be reset just the same, to maybe be
    started after the timeout fires up.
