MediaStreamTrack.muted flag should not be modified when `enabled` flag is changed

[aszmyd]

Expected behavior

MediaStreamTrack.muted property should not rely on MediaStreamTrack.enabled property.

Observerd behavior

Opposite to above - when toggling MediaStream.enabled flag, muted flag also gets toggled.

Steps to reproduce the problem

navigator.mediaDevices.getUserMedia({audio: true}).then(stream => {
                console.log('--1:', JSON.stringify(stream.getAudioTracks()));
                stream.getAudioTracks().forEach(track => track.enabled = false);
                console.log('--2:', JSON.stringify(stream.getAudioTracks()));
                stream.getAudioTracks().forEach(track => track.enabled = true);
                console.log('--3:', JSON.stringify(stream.getAudioTracks()));
});

I see this output:

04-07 14:58:11.057 17736 17795 I ReactNativeJS: '--1:', '[{"_constraints":{},"_enabled":true,"id":"60751b32-53f5-45b3-bc56-de77c3732fda","kind":"audio","label":"60751b32-53f5-45b3-bc56-de77c3732fda","muted":false,"remote":false,"readyState":"live"}]'

04-07 14:58:11.059 17736 17795 I ReactNativeJS: '--3:', '[{"_constraints":{},"_enabled":true,"id":"60751b32-53f5-45b3-bc56-de77c3732fda","kind":"audio","label":"60751b32-53f5-45b3-bc56-de77c3732fda","muted":false,"remote":false,"readyState":"live"}]'

But would assume muted property should not be changed as according to docs: https://developer.mozilla.org/en-US/docs/Web/API/MediaStreamTrack/muted it means device is somehow not able to produce audio. For simple "muting", enabled flag is used:

To implement a way for users to mute and unmute a track, use the enabled property. When a track is disabled by setting enabled to false, it generates only empty frames (audio frames in which every sample is 0, or video frames in which every pixel is black).
