How to keep angle of DropShadow when node is rotated - javafx

Question

When you apply a DropShadow on a node which is rotated, then the DropShadow rotates with it. Is there a simple way to keep the DropShadow angle where it is, e. g. bottom right even when the node is rotated?
I know that it would work if I put all the nodes into a group and apply the shadow on the group, but that's unfortunately not an option in my case.
Sample image:
left rectangle with drop shadow
right rectangle with same drop shadow, but rotated by 180 degrees
You see, it looks wrong with the shadows being in opposite directions.
Code
public class HelloEffects extends Application {
Stage stage;
Scene scene;
#Override
public void start(Stage stage) {
Group group = new Group();
DropShadow ds1 = new DropShadow();
ds1.setOffsetY(4.0f);
ds1.setOffsetX(4.0f);
ds1.setColor(Color.BLACK);
Rectangle rect1 = new Rectangle( 100, 200);
rect1.relocate(100, 100);
rect1.setEffect(ds1);
rect1.setFill(Color.RED);
Rectangle rect2 = new Rectangle( 100, 200);
rect2.relocate(300, 100);
rect2.setEffect(ds1);
rect2.setFill(Color.RED);
rect2.setRotate(180);
group.getChildren().addAll(rect1, rect2);
scene = new Scene( group, 840, 680);
stage.setScene(scene);
stage.show();
}
public static void main(String[] args) {
Application.launch(args);
}
}

You should add a container to rect2 and apply the effect on the container, the container can be either Pane or Group:
Group rect2Container = new Group(rect2);
rect2Container.setEffect(ds1);
group.getChildren().addAll(rect1, rect2Container);
