Describe the bug

What I'm expecting

Participant A enters a room, shares the screen and enables the camera (a participant B is already in the room). Participant B sees the screen shared AND the camera.

What happens instead

Participant A enters a room, shares the screen and enables the camera (a participant B is already in the room). Participant B sees the screen shared but NOT the camera.

1. Participant A enters a room.
2. Participant B enters a room.
3. Participant A shares the screen.
4. Participant B can see the screen shared.
5. Participant A enables the camera.

Reproduced with the VideoConference component.

I just tried this on meet.livekit.io and following your repro steps. And B can see the camera of A.

Can you reproduce this there as well?
If so, please post logs.

What is the browser and the version?

[adcimon]

Participant A: Firefox 124
Participant B: Chrome 122.0.6261.129

Reproduced on meet.livekit.io.
It doesn't happen if the participant B (Chrome) is the one who shares. Seems an issue with Firefox.
