    window: Don't constrain an acked window geometry
    
    In Wayland, window configuration is asynchronous. Window geometry is
    constrained, the constrained geometry is sent to the client, and the
    client will adapt its surface and acknowledge the configuration. When
    acknowledged, we shouldn't reconstrain again, as that may invalidate the
    constraint calculated for the configured size.
