Calling gUM with a facingMode constraint has regressed in 60. Bug 1299515 is the likely suspect so marking it for now.

Is there really no better pattern for > this? The proper way IMO would be to do these checks in the platform backend and signal them up to the MediaEngineSource through IPC. At least on Android this is provided by the system APIs.   A simpler fix to remove the footgun here could be to lift this logic out to a local function that takes a string (the device name) and returns a `Maybe<VideoFacingModeEnum>`. Feel free to file followups for either of these approaches.  https://developer.android.com/reference/android/hardware/Camera.CameraInfo.html#facing  https://developer.android.com/reference/android/hardware/camera2/CameraCharacteristics.html#LENS_FACING
