Showing ComboBox doesn't select next focusable on tab

[MaggdaDev]

In contrary to desktop version, clicking on combobox and pressing TAB does not focus the next focusable node.

package one.jpro.hellojpro;

import javafx.application.Application;
import javafx.collections.FXCollections;
import javafx.scene.Scene;
import javafx.scene.control.ComboBox;
import javafx.scene.control.TextField;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;
public class HelloJPro extends Application {

    @Override
    public void start(Stage stage) {
        ComboBox comboBox = new ComboBox(FXCollections.observableArrayList("A"));
        TextField textField = new TextField();
        Scene scene = new Scene(new VBox(comboBox, textField));
        stage.setScene(scene);
        stage.show();
    }

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

Improved test programm independent of combobox. EventRedirector in PopupWindow is the suspect for the issue.

package one.jpro.hellojpro;

import javafx.application.Application;
import javafx.event.ActionEvent;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.control.Label;
import javafx.scene.control.TextField;
import javafx.scene.layout.StackPane;
import javafx.scene.layout.VBox;
import javafx.stage.Popup;
import javafx.stage.Stage;

public class HelloJPro extends Application {

    @Override
    public void start(Stage stage) {
        Button b = new Button("popup");
        b.setOnAction((ActionEvent event) -> {
            Popup popup = new Popup();
            popup.getContent().add(new StackPane(new Label("L")));
            popup.show(stage);
            popup.setY(popup.getY() + 200);
        });
        Scene scene = new Scene(new VBox(b, new TextField()));
        stage.setScene(scene);
        stage.show();
    }

    /**
     * Application entry point.
     *
     * @param args the command line arguments
     */
    public static void main(String[] args) {
        launch(args);
    }
}
