Reproduce the issue with mayavi/examples/mayavi/interactive/subclassing_mayavi_application.py, focusing on line 67 where a.marker.set_viewport is called. Read the OrientationMarkerWidget API and the surrounding example code to identify the supported viewport interface. Done means the example runs without this AttributeError and the marker still appears in the intended viewport.
