I thought about this as well but could not find any problem at least on Windows.
If we want to be perfectly safe, we may still want to set the flag when `sizeToScene()` is called. What do you think?

I used the following code to test this, and it didn't matter when `sizeToScene()` was called:


   @Override
    public void start(Stage primaryStage) throws Exception {
        StackPane root = new StackPane();
        Button wss = new Button("Wss");
        wss.setPrefSize(50, 50);
        root.getChildren().add(wss);

        Scene scene = new Scene(root);

        Stage stage = new Stage();
        stage.setWidth(500);
        stage.setMaximized(true);
        stage.sizeToScene();
        stage.setScene(scene);
        stage.show();
    }
