Safari audio tracks not disabling correctly

[kg-jcaron]

Joining a room with a disabled audio track on desktop safari 18.1, and ios safari 17.0, 18.0, and 18.1 treats the track as enabled and all audio is broadcast to the rest of the participants. The LocalAudioTrack.isEnabled property returns false, but the audio is broadcast. Enabling the track, and then re-disabling it fixes the issue. This doesn't seem to occur in iOS 16.0, or on desktop Chrome or Firefox.

I made a reproduction example using the video-quickstart-js repo (the localmediacontrols example http://localhost:3000/localmediacontrols/): https://github.com/kg-jcaron/video-quickstart-js

Hi, this is a known issue on WebKit (https://github.com/WebKit/WebKit/commit/c29f5f0e0f7e949d33dd3457e4e44609a7a7219b). However, we are working on a workaround to mitigate this for our SDK users. See https://github.com/twilio/twilio-video.js/pull/2061 for more details.
