Permissions popup is not shown if `audio=true`

Please follow the general troubleshooting steps first:

• [x] Is your app running over HTTPS? (please provide the URL if possible)
• [x] Have you tried running the demo (https://codepen.io/mozmorris/pen/JLZdoP) on your device?
• [x] Checked the latest "Can I use" compatbility table? (https://caniuse.com/stream)

Currently we see following:

GIVEN we have simple case like this:

<Webcam audio />

AND user has microphone permission on the system turned off for google chrome WHEN user goes to the camera page THEN the permissions popup is not shown AND camera is not working

Tested on iphone and android devices with chrome, both behave same way as described above. Had couple of desktop complaints too.

My question is, is this an intended behavior or should permissions popup be always shown?

@chalagashvili if permissions are switched off at a system level, a popup will not appear.

I have just tested this on an iPhone running the latest iOS. If I "Deny" audio and camera, no popup. If I set to "Ask", the permissions popup appears.

Note, this is not something react-webcam specific but related to any application using the getUserMedia api.
