JavaFX controls not receiving mouse events when also using Shape3D

I'm working on a ScalaFX application that has both controls and models in the same window (it is a game). Unfortunately, when I add the models, the controls stop receiving mouse events even though the two do not overlap. A smallest working example looks like this:

import scalafx.Includes._
import scalafx.application.JFXApp
import scalafx.application.JFXApp.PrimaryStage
import scalafx.scene._
import scalafx.scene.control._
import scalafx.scene.input.MouseEvent
import scalafx.scene.layout._
import scalafx.scene.shape._

object GameWindow extends JFXApp {
  stage = new PrimaryStage {
    scene = new Scene(800, 600, true, SceneAntialiasing.Balanced) {
      root = new VBox(
        new Button("Click me!") {
          handleEvent(MouseEvent.MouseClicked) {
            me: MouseEvent => Console println "clicked!"
          }
        },
        new Sphere() {
          radius = 100
        })
    }
  }
}

If I replace the sphere with a 2D shape, like Circle or Rectangle, the controls become responsive again; it is only a problem when I add 3D shapes. I have tried setting mouseTransparent and clearing pickOnBounds on the Sphere, but neither seem to work.

How can I let the controls continue to receive mouse events when they are clicked? It is acceptable for the models to not receive them.

When mixing 2D (controls) and 3D content you should wrap the 3D content in a SubScene, for instance like this:

object GameWindow3D extends JFXApp { stage = new PrimaryStage { scene = new Scene(800, 600, true, SceneAntialiasing.Balanced) { root = new VBox( new Button("Click me!") { handleEvent(MouseEvent.MouseClicked) { me: MouseEvent => Console println "clicked!" } }, new SubScene(400, 400, true, SceneAntialiasing.Balanced) { root = new VBox { children = new Sphere() { radius = 100 } } } ) } } }
