Hologram Navigation Gesture gaze issue

Using the InputManager prefab from the HoloToolkit and this code:

    [Tooltip("Rotation max speed controls amount of rotation.")]
    public float RotationSensitivity = 2.0f;

    private float rotationFactor, rotationFactor2;

    public void OnNavigationStarted(NavigationEventData eventData)
    {
        Debug.Log("Navigation is started");
    }
    public void OnNavigationUpdated(NavigationEventData eventData)
    {
        rotationFactor = eventData.CumulativeDelta.x * RotationSensitivity;

        rotationFactor2 = eventData.CumulativeDelta.y * RotationSensitivity;

        if (System.Math.Abs(eventData.CumulativeDelta.x) > System.Math.Abs(eventData.CumulativeDelta.y))
        {
            transform.Rotate(new Vector3(0, -1 * rotationFactor, 0));
        }
        else
        {
            transform.Rotate(new Vector3(-1 * rotationFactor2, 0, 0));

            //if this control structure doesnt work, try setting the other value to zero instead
        }

        Debug.Log("event X: " + eventData.CumulativeDelta.x);
        Debug.Log("event Y: " + eventData.CumulativeDelta.y);

    }
    public void OnNavigationCompleted(NavigationEventData eventData)
    {
        Debug.Log("Navigation is completed");
    }
    public void OnNavigationCanceled(NavigationEventData eventData)
    {
        Debug.Log("Navigation is canceled");
    }

The user can tap and hold and move their hand left or right (x-plane) to rotate along the Y axis and up and down (y-plane) to rotate the object on the X axis.

However there appears to be a bug. If the users gaze comes off the object, the rotation stops immediately until the users gaze returns to the object. Is this the intended functionality? Is there a way to preserve the current object being changed via the navigation gesture and allow it to continue being manipulated until the users hand leaves the FOV or releases the tap and hold?

Ok. Clear the stack on Navigation started, InputManager.Instance.ClearModalInputStack();, then push it onto the stack, InputManager.Instance.PushModalInputHandler(gameObject); and on navigation completed or canceled pop it, InputManager.Instance.PopModalInputHandler();

In your own implementation.
