I don't think this is needed.  Does your test fail if you remove this line?

The test passes fine without this. I only added it because WheelController was

             if (RuntimeEnabledFeatures::deviceMotionEnabled())
                 DeviceMotionController::from(*document);
             if (RuntimeEnabledFeatures::deviceOrientationEnabled())
