    csswidgetnode: Don't check for container
    
    The conditions to queue and dequeue a CSS validation
    are different; while queueing checks if the widget is
    a root, dequeueing checks that AND if the widget is
    a container.
    
    GtkWindow is not a GtkContainer anymore, and that is
    causing validations to be queued, but never dequeued.
    
    Don't require the widget to be a GtkContainer for
    dequeuing.
