Losing audio track following a webRTC Glare detection

• [X] I have verified that the issue occurs with the latest twilio-video.js release and is not marked as a known issue in the CHANGELOG.md.
• [X] I reviewed the Common Issues and open GitHub issues and verified that this report represents a potentially new issue.
• [X] I verified that the Quickstart application works in my environment.
• [X] I am not sharing any Personally Identifiable Information (PII) or sensitive account information (API keys, credentials, etc.) when reporting this issue.

Context: Two parties are contacting each other via twilio video in the browser. One is called the ‘expert’, and the other the ‘customer’. The customer publishes only audio and data channels. The expert publishes audio, video and data.

The customer and expert both connect to the room and publish their channels. When they connect - on some connections the expert is unable to hear the customer. The issue only arises 1 out of every 20-100 runs.

Technology: The application we have built is based on the react sample code. When the expert navigates to our page - they connect to the twilio room, then (because of the behaviour of our app and the twilio hooks) immediately independently publishes data, audio and video tracks (more or less in parallel). A similar thing will happen on the customers machine at approximately the same time. We have turned on twilio logging.

Observation Whenever the customer's sound is not present - it is always accompanied by a 'Glare detected; rolling back' twilio log entry on the customer's machine. On the expert's machine the audio initially mounts, but we quickly receive a MediaStreamTrack ended event and audio tag's srcObject active becomes false. The broker cannot hear any sound from the customer We receive no further events regarding additional MediaStreams / Tracks being published/started

Log Files I cannot supply any code, but have attached relevant fragments of the twilio log file in the attached excel.
