sample to try this problem

We noticed problem with audio during webrtc call on inactive tab.

Situation:
- User is in the webrtc active call from safari. But this user is doing something on another tab (e.q. shares that tab, reads some information or whatever)
- another user joins that call, so new audio track is received but there no any way to play that track (because tab is inactive)

I created little sample to reproduce this.
- open example
- press start
- open another tab and wait (near 10 seconds)
result:
- no audio

this works fine in chrome but not in safari.

Issue is valid for macos and ios.

I'm wondering is it some kind of safari limitation? or this is a bug?
