JavaFX Webview: addEventListener for clicks NOT on an hyperlink?

In WebView, is there a way to execute a function for any click NOT on an given hyperlink?

I tried to add an event handler on the WebView to always execute the function, and then add an event listener to hyperlinks in an attempt to consume the event. However, event.preventDefault() and event.stopPropagation() don't actually stop the event, so the function is still executed when an hyperlink is clicked.

In this example, the message is still printed when an hyperlink is clicked:

import javafx.application.Application;
import javafx.concurrent.Worker;
import javafx.scene.Scene;
import javafx.scene.input.MouseEvent;
import javafx.scene.layout.VBox;
import javafx.scene.web.WebView;
import javafx.stage.Stage;
import org.w3c.dom.Document;
import org.w3c.dom.NodeList;
import org.w3c.dom.events.EventListener;
import org.w3c.dom.events.EventTarget;

public class Main extends Application {
    public static void main(String[] args) { launch(args); }

    public void start(Stage primaryStage) {
        // Setup the WebView
        WebView webView = new WebView();
        String content = "<br>some text<br> a link: <a href='www.google.com'>google</a></body>";
        webView.getEngine().loadContent(content);

        // Add the hyperlink listener
        webView.getEngine().getLoadWorker().stateProperty().addListener(
                (o, old, state) -> {
                    if (state != Worker.State.SUCCEEDED) { return; }

                    // Create the event listener
                    EventListener listenerA = event -> {
                        System.out.println("Attempting to block the click");
                        // Doesn't actually block the click
                        event.preventDefault();
                        event.stopPropagation();
                    };

                    Document doc = webView.getEngine().getDocument();
                    // Add event handler to <a> hyperlinks.
                    NodeList nodeList = doc.getElementsByTagName("a");
                    for (int i = 0; i < nodeList.getLength(); i++) {
                        EventTarget hyperlink = (EventTarget) nodeList.item(i);
                        hyperlink.addEventListener("click", listenerA, true);
                    }
                });
        // Add the click listener
        webView.addEventHandler(MouseEvent.MOUSE_CLICKED,
                event -> System.out.println("I want this to be printed only when a click occurs outside an hyperlink"));

        // Setup the scene
        VBox vBox = new VBox(webView);
        Scene scene = new Scene(vBox, 960, 600);
        primaryStage.setScene(scene);
        primaryStage.show();
    }
}

I'm trying to do this because I use WebView as a transparent overlay for my Swing UI; I have clicks forwarded to the Swing components but I want to not forward clicks to Swing if the user clicks on an overlay hyperlink.
