Karl Tomlinson ae8f8e7132 Bug 1753131 - Dispatch devicechange events even without an actively capturing MediaStreamTrack r=jib
"fully active and has focus" is now a sufficient condition for dispatching "devicechange" events if the change in devices should be visible from enumerateDevices().
https://github.com/w3c/mediacapture-main/pull/574/files#diff-1217ca1c44ff30a33dd50c49d03b5cadc9633c789df8ff9370ed4a42859e1211R3146

Permissions checks are replaced with [[canExposeCameraInfo]] and [[canExposeMicrophoneInfo]] slots set by getUserMedia().
https://github.com/w3c/mediacapture-main/pull/641
https://github.com/w3c/mediacapture-main/pull/773

The "media.navigator.permission.disabled" pref is no longer involved in "devicechange" dispatch decisions.
