webXR AR broken on Android Chrome 88

Describe the bug

My test device runnning Android 8.0.0 updated to Android Chrome 88 today, and the three XR AR samples no longer work.

I am describing the issue on the webxr_ar_hittest example.

To Reproduce

Steps to reproduce the behavior:
-Update Android Chrome to v88.
-Go to https://threejs.org/examples/?q=webXR#webxr_ar_hittest
-Click on “Start AR”.
-This is not working and there is an error in the console.

Expected behavior
We should go in AR (it was working before with Chrome <88).
