如何让JavaFx TabPane title成为WebView的站点标题？

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Tab;
import javafx.scene.control.TabPane;
import javafx.scene.web.WebEngine;
import javafx.scene.web.WebView;
import javafx.stage.Stage;

public class Main extends Application {

    @Override
    public void start(Stage primaryStage) {
        TabPane tabPane = new TabPane();

        Tab tab = new Tab();
        WebView webView = new WebView();
        tab.setContent(webView);
        tabPane.getTabs().add(tab);

        WebEngine webEngine = webView.getEngine();
        webEngine.load("https://www.example.com");

        webEngine.getLoadWorker().stateProperty().addListener((observable, oldValue, newValue) -> {
            if (newValue == Worker.State.SUCCEEDED) {
                String title = webEngine.getTitle();
                tab.setText(title);
            }
        });

        Scene scene = new Scene(tabPane, 800, 600);
        primaryStage.setScene(scene);
        primaryStage.show();
    }

    public static void main(String[] args) {
        launch(args);
    }
}
