Cannot scroll JavaFX ComboBox of Strings on Android device

Question

I have a Combo Box of Strings within my JavaFX Application.

When I open the ComboBox using desktop, everything is fine, works normally.

When I port to Android using javafxports, I cannot scroll, when I try, the box closes.

Here is a video of the issue: https://www.youtube.com/watch?v=YWGzKrHhZQs

GitLab Repo of code to replicate the issue: https://github.com/mattlewer/basicComboIssue/tree/master/GluonScroll

Main Class:

package com.gluonapplication;

import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.geometry.Rectangle2D;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Screen;
import javafx.stage.Stage;


public class GluonApplication extends Application {

    @Override
    public void start(Stage primaryStage) throws Exception{

        // Loads the FXML and gets the controller
        FXMLLoader loader = new FXMLLoader(getClass().getResource("/assets/basicViewFXML.fxml"));
        Parent root = (Parent)loader.load();
        BasicView basic = loader.getController();

        // Prepare comboBox contents
        String skills[] = {"Overall", "Agility", "Attack", "Construction", "Cooking", 
         "Crafting", "Defence", "Farming", "Fishing", "Fletching", "Herblore",
         "Hitpoints", "Hunter", "Prayer", "Magic", "Mining", "Firemaking",  "Ranged", 
         "Runecraft", "Slayer",  "Smithing",  "Strength",  "Thieving", "Woodcutting" };
        // Add contents to drop down comboBox
        for(String s : skills){
            basic.comboBox.getItems().add(s); 
        }

        // Set Scene
        Scene scene = new Scene(root);
        primaryStage.setScene(scene);

        // Set the size of our app the the size of the users screen and show
        Screen screen = Screen.getPrimary();
        Rectangle2D bounds = screen.getVisualBounds();
        primaryStage.setX(bounds.getMinX());
        primaryStage.setY(bounds.getMinY());
        primaryStage.setWidth(bounds.getWidth());
        primaryStage.setHeight(bounds.getHeight());
        primaryStage.show();
    }

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

EDIT: After moving the ComboBox to the 'Top' section of the BorderPane, scrolling now works for the top left quarter, but not the rest, very weird behaviour https://www.youtube.com/watch?v=D6CKjlNjYh8
