if alice is hidden, the other players should not subscribe alice, where is this logic, https://github.com/livekit/livekit-server/blob/61655c6ff05625ecd86557711cec38a4a9f7167d/pkg/rtc/participant.go#L243 , I can not tell difference between visible ones and invisible ones.

it will trigger sending offer sdp regardless self is visible or not
