I'm retesting and writing tests right now and reproduced one usecase out of my head that indeed 'fails' now.
Take the following code:

        Button button = new Button();
        button.setMinSize(440, 440);

        Scene scene = new Scene(button);
        stage.setTitle("JavaFX test stage!");
        stage.setScene(scene);

        stage.setWidth(50);
        stage.setHeight(50);

        stage.setFullScreen(true);
        stage.sizeToScene();
        stage.setFullScreen(false);

        stage.show();


With my logic, the `sizeToScene()` flag is not remembered, so the scene is not adjusted in the `sizeToScene` style after I 'go out' of fullscreen mode.

If I do instead:

        stage.sizeToScene();
        stage.setFullScreen(true);
        stage.setFullScreen(false);


The flag is remembered and the scene has the size of the button. Not sure what the expectation is here, but we could fix this problem by still remembering the flag if called.
