webXR AR broken on Android Chrome 88

[jtanant]

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.
https://threejs.org/examples/?q=webXR#webxr_ar_cones
https://threejs.org/examples/?q=webXR#webxr_ar_hittest
https://threejs.org/examples/?q=webXR#webxr_ar_paint

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).

Screenshots

Platform:

• Device: Mobile
• OS: Android 8.0.0

Can you please try it with the current dev version?

Same result?

Tried it myself on a Pixel 4a. The dev version works (because of #20754). So this will be fixed with r125 next week.

Yes... It's unfortunate, but seems like Chrome 88 broke all the projects done pre-r125 🙁

Thanks for such a prompt answer @Mugen87 and @mrdoob !
Yes, I am confirming it works on my side with dev version.
Let's migrate our project and keep up the good work!

They must have made a slight tweak to how promises are resolved.

Well, at least #20754 is not a big PR. If a project can't afford the budget to upgrade to the latest three.js version, they can still cherry-pick the change into their build. Not ideal but better than a broken app...
