Steps to reproduce the problem:
1. Reset the "Camera" and "MicroPhone" permission from the terminal ("tccutil reset Camera" and "tccutil reset Microphone" helps resetting permission)
2. Invoke the getUserMedia API, please use this jsfiddle page https://jsfiddle.net/r60bzmrs/65/
3. Allow the browser permission to access Camera and Microphone, (If it was not available)
4. If the browser permission is allowed, now OS prompt for Camera and then for Microphone permissions.
5. Choose "Don't Allow" for Camera permission and allow for the Microphone permission,
6. Now Re run the same code, the getUserMedia API is rejected with an error "Not readable error",

What is the expected behavior?
The Browser should give audio stream as the Microphone permission was allowed by the user. 

What went wrong?
No stream received, as the camera permission is denied by the user.

Did this work before? N/A 

Does this work in other browsers? N/A
