I need to set CSS Id on Tab at run-time, but ot seems like it doesn't work.
I can set Id before stage is shown, but after that tab remains previous style.

public void start(Stage primaryStage) throws Exception {
        TabPane tabPane = new TabPane();

        Tab first = new Tab("I'm red");
        first.setId("red");
        first.setClosable(false);

        Tab second = new Tab("I wanna be red");
        second.setClosable(false);
        Button button = new Button("Make it red");
        button.setOnAction( e-> {
            second.setId("red");
            button.setId("red");
        });
        second.setContent(button);

        tabPane.getTabs().addAll(first, second);

        Scene scene = new Scene(tabPane);
        scene.getStylesheets().add("Example.css");
        primaryStage.setScene(scene);
        primaryStage.show();
    }

Example.css:
#red {
    -fx-background-color: red;
}
