Description

If a conference participant using a Safari browser navigates away from the conferencing app to another tab and a new participant joins the call, the Safari participant will not hear the new participant until they navigate back to the conferencing App tab. This only happens on dolbyVoice:false conferences.  

Reproduction Steps

1. Join a conference with the Safari browser.
2. Have at least one other participant join and confirm that two-way voice works normally.
3. Navigate to another tab.
4. Have another participant join the conference.
5. Confirm that the new participant cannot hear the Safari user, that audio to the new participant is now one-way.
6. Navigate back to conferencing App tab.
7. Confirm that two-way audio works normally.
