Positional tracking in Oculus Browser WebVR worse than native

Hi there,

Thanks for all the great work on the Oculus Browser! I believe I'm seeing significantly worse positional tracking in the WebVR browser compared to native apps.

To reproduce:
  • Visit http://moonrider.xyz using the Oculus Browser on Quest
  • Click to enter VR (glasses icon in bottom right corner)
  • Bend knees and move whole torso from left to right (i.e. left/right DoF, not yaw)
  • Notice the edges of things like the 'Start' button and the grey star you are standing on (look down) move in a choppy way
To compare:
  • Open Beat Saber demo and start tutorial
  • Move to the corner of the black square you are standing on (with the white edge) and look down
  • Repeat same left/right movement
  • Notice the white edges of the square do not move in a choppy way
So it appears the WebVR browser has a lower frequency of positional tracking than the native apps. Is this something that can be fixed?

Note: MoonRider is one example, but it happens generally with any WebVR app. For example in https://aframe.io/aframe/examples/showcase/anime-UI/ if you move your torso left/right while looking at the white circles against the blue background

I tried toggling the 'highRefreshRate' flag but it appears that's already set automatically (if I measure the FPS it's 72). And I tried 'foveationLevel' but that didn't help either.
