Describe the bug

Subscribers cannot chat in subscriber-only chats when in embed tl mode. They can still chat in "watch in livetl" mode and in hyperchat. Disabling all other extensions does not fix.

Steps To Reproduce

1. go to a stream with subscriber only chat of a streamer you are subscribed to
2. open ltl embed
3. notice that the chat says "subscriber only" and doesn't let you, the subscriber, chat

Expected behavior
