Camera positions for non-webxr and WebXR don't face the front and centre

I’m trying to find ways to get the camera for video to face the front and centre. And also make webxr face the front and centre by default. You can see my tests in this ticket uncorrected non-webxr camera faces the ground and WebXR camera faces 90 degrees to the right. Corrected using the camera position it needs to remove 0.85 from the Y rotation to face the exact centre and its different for each video. It would be good to not have to correct non-webxr camera changing the x position.
