--- Comment #32 from rooke at mash.com ---
This can reliably be reproduced with the following device:

Model Number: MXCX2VC/A
iOS Version 16.5

Method: 
1) Open up an PWA that uses the camera.
2) Use the camera (however the PWA uses it, ultimately calling navigator.mediaDevices.getUserMedia()). It works normally.
3) Go to the app selection carousel (via swipe up from bottom, or double-tapping home button)
4) Swipe up on the PWA app's preview to close the app.
5) Open up the PWA app again
6) Go to the camera. It will be black/not showing. The following is returned from a call to navigator.mediaDevices.getUserMedia({ audio: false, video: true }):

MediaStreamTrack: {
contentHint: ""
enabled: true
id: <a-uuid-redacted>
kind: "video"
label: "Front Camera"
muted: true
onconfigurationchange: null
onended: null
onmute: null
onunmute: null
readyState: "live"
}
