Cached Transition on translateXProperty 'disappears' at 90 degree rotation

When using a Timeline transition on a translateXProperty of a shape, the image disappears when the container is rotated to 90 degrees (and other 'vertical' angles) AND setCache(true) is used. 89 degrees works fine. Code to demonstrate follows:


package application;

import javafx.animation.KeyFrame;
import javafx.animation.KeyValue;
import javafx.animation.Timeline;
import javafx.application.Application;
import javafx.geometry.Insets;
import javafx.scene.CacheHint;

import javafx.scene.layout.HBox;
import javafx.scene.layout.Priority;
import javafx.scene.layout.Region;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;
import javafx.util.Duration;

public class Main extends Application
{

    // The meat of the problem is here ...
    // If we choose a combination of setCache(true) and a 90 degree rotation (or multiple thereof) the image disappears
    private void startAnimation()
    {
        disableSwitches(true);

        if (cacheCheckBox.isSelected()) {
            shuttle.setCache(true);
            shuttle.setCacheHint(CacheHint.SPEED);

        } else {
            shuttle.setCache(false);
            // shuttle.setCacheHint(null);
        }

        field.setRotate(rotationComboBox.getValue());

        timeline =
                new Timeline(new KeyFrame(Duration.millis(Double.valueOf(durationField.getText())),
                        new KeyValue(shuttle.translateXProperty(), 370),
                        new KeyValue(shuttle.cacheHintProperty(), CacheHint.SPEED)));

        timeline.setCycleCount(Timeline.INDEFINITE);
        timeline.setAutoReverse(true);
        timeline.play();
    }

    private void stopAnimation()

        timeline.stop();
