When adding echoCanellation:false to audio constraints for getUserMedia to capture a mono audio device, the returned mediaStreamTrack is stereo but has left channel audio only. Enabling AEC against the same device results in 2 channel audio. Same against Safari iOS/17.6.1 and Safari 18.0/MacOS 15.0

To add, channelCount value in constraints has no effect, but if channelCount is omitted there is no audio on the track at all
