In WebVR one could simply use camera.getWorldDirection() to find the direction in which the camera is pointed in VR. As of r113, in WebXR this same call returns information about the parent rig of the camera, rather than the camera, at least in Oculus browser on both Quest and Go.

The culprit is the line this.updateMatrixWorld( true ) in the function, because without it the correct camera information is returned. I can't see any recent changes in camera.updateMatrixWorld that would cause the change. Is this just expected behavior in WebXR vs WebVR? If so then camera.getWorldDirection is not useful in this context.
