WKWebView getUserMedia regression between iOS 15.5 and 16 beta 3

Minimum repro test: https://webrtc.github.io/samples/src/content/getusermedia/gum/
Expectation: User clicks "Open Camera", user allows camera permissions, camera feed is displayed 
Result: Camera feed is not displayed when camera permissions are allowed (frame remains black)

As a result of this bug, Niantic WebAR sites are broken impacting major brands including: Paramount Pictures, Universal Pictures, Marvel, LA Dodgers, MGM, Xbox, & More

Video attached showing unexpected behavior in Chrome WKWebView on iPhone 11 running iOS 16 beta 3.

Example of impacted Paramount Pictures website (Opened in WKWebView): https://whatsmycallsign.com
Expected result: After user enters their name, and allows camera permissions, they see their front camera feed with an AR face effect. 
Actual result on iOS 16 beta 3 WKWebVIew: User enters their name, allows camera permissions, the camera feed is not displayed

Recategorizing as Media rather than WebGL bug. The given test case doesn't touch WebGL; it only feeds the stream from getUserMedia intoa. video element.
