PopOver has infinite layout passes when adding line border with title

[jperedadnr]

Run the following simple test case with current ControlsFX 11.2.0 and JavaFX 21.0.2:

import javafx.application.Application;
import javafx.scene.Node;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.control.Label;
import javafx.scene.layout.Pane;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;
import org.controlsfx.control.PopOver;
import org.controlsfx.tools.Borders;

public class PopOverTest extends Application {

    @Override
    public void start(final Stage primaryStage) {
        final Button button = new Button("Button");
        final StackPane root = new StackPane(button);
        button.setOnAction(e -> {
            final PopOver popOver = new PopOver();
            StackPane pane = new StackPane(new Label("Text"));
            Node node = Borders.wrap(pane).lineBorder()
                    .buildAll();
            ((Pane) node).needsLayoutProperty().addListener((obs, ov, nv) -> System.out.println("needs layout = " + nv));
            popOver.setContentNode(node);
            popOver.show(root);
        });
        Scene scene = new Scene(root, 200, 100);
        primaryStage.setScene(scene);
        primaryStage.show();
    }
}

Click on the button to show the popOver control and see the output:

needs layout = false
needs layout = true
needs layout = false

That's it (as expected).

Now add a title to the border:

            Node node = Borders.wrap(pane).lineBorder()
                     .title("Title")
                    .buildAll();

run again:

and check the output:

needs layout = false
needs layout = true
needs layout = false
needs layout = true
needs layout = false
needs layout = true
needs layout = false
needs layout = true
needs layout = false
needs layout = true
...

it doesn't stop while the popup is showing up.

(This can be reproduced on all platforms)
