Issue 824937  has been merged into this issue.

Need to create a Manual Testcase to cover the polyfill, based on the M65 issue https://bugs.chromium.org/p/chromium/issues/detail?id=819413

Also need to think about the WebVR-to-WebXR polyfill, which does depend on our APIs.

Adding labels from a duped bug.

We've had several breaks where Chrome behavior changes/bugs break the polyfill, and we don't realize until close to shipping.

We should test the polyfill on recent pre-stable Chrome to find and address issues earlier.

Example areas to look at:
* generic sensors, fallback
* device motion
* xr over vr, vr over xr
* rendering/canvas
* iframes, focus, cross-origin/same-origin, feature policy, oopif

Could automate or do manual.
