setting orientation in scene does not propagate

not sure if this is bug or not, but setting node orientation in scene does not change what is inside of it.

Basically:
scene.addEventFilter(KeyEvent.KEY_PRESSED, new EventHandler<KeyEvent> () {
    @Override public void handle(KeyEvent event) {
        if (event.getCode() == KeyCode.LEFT) {
            scene.setNodeOrientation(NodeOrientation.LEFT_TO_RIGHT);
        }
        if (event.getCode() == KeyCode.RIGHT) {
            scene.setNodeOrientation(NodeOrientation.RIGHT_TO_LEFT);
        }
        System.err.println("orientation " + scene.getNodeOrientation());
    }
});

does not change the content of the scene

I have to do this

scene.addEventFilter(KeyEvent.KEY_PRESSED, new EventHandler<KeyEvent> () {
    @Override public void handle(KeyEvent event) {
        if (event.getCode() == KeyCode.LEFT) {
            scene.getRoot().setNodeOrientation(NodeOrientation.LEFT_TO_RIGHT);
        }
        if (event.getCode() == KeyCode.RIGHT) {
            scene.getRoot().setNodeOrientation(NodeOrientation.RIGHT_TO_LEFT);
        }
        System.err.println("orientation " + scene.getNodeOrientation());
    }
});
