Tested on iPhone 7, iOS 13.4
Open Mobile Safari and go to https://milen-yordanov.github.io/webrtc-ios13_4-enumerateDevices/
The first call to enumerateDevices() reports two devices: videoinput and audioinput.
The second call to enumerateDevices() reports two devices: audioinput and audioinput. There is no videoinput!
The code to reproduce it is as simple as:
await navigator.mediaDevices.enumerateDevices()
await navigator.mediaDevices.enumerateDevices()
See: https://raw.githubusercontent.com/milen-yordanov/webrtc-ios13_4-enumerateDevices/master/index.html
Older iOS 13.x and 12.x did not have this issue.

There are a number of workarounds:
- On iOS, all devices running Safari should have a camera.
- Add a shim to enumerateDevices so as to buffer the result of enumerateDevices until capture is granted/devicechange event is fired.
