Quick Look AR not accessible in in-app browers // iOS 15.8

Will AR Quick Look support be provided via in-app browsers on iOS 15? The most recent update of iOS 15 doesn't provide this functionality. The user sees a greyed out AR button. The Object mode works as expected, however.

To replicate:

  1. Send this link (https://www.apple.com/events) to the Gmail app, or message it to yourself in Slack or Discord
  2. Open it
  3. Tap on the Apple logo

This is what you see in in-app browsers after launching a USDZ link:

I've created a bugzilla ticket as well: https://bugs.webkit.org/show_bug.cgi?id=230023

I just noticed this problem too when I upgrade my phone to iOS 15.3. All the usdz file I have on my phone now only display in "Object" mode but not "AR" mode. This is really big regression, please let us know when the issue is addressed.

Just a random guess, maybe somehow AR Quicklook doesn't have permission to access the camera anymore after some conventions changed with the OS update?
