Community server global chat relaying to Singleplayer game

Joined a community server, then logged out and entered a singleplayer game. For a while, the global chat from the community server was relaying to my singleplayer game, but then stopped after a moment. When trying to reproduce this bug, chat had disabled itself for global, group, and local in both the community server as well as singleplayer. I'd also like to note that my video did not capture the chat actively relaying, as it had stopped by the time I managed to get OBS open to clip it. (I also apologize for not cleaning my video clip up, it may go on longer than necessary as I had tabbed out to file this)

Global chat had not cleared as it usually does when entering a singleplayer game, instead it carried over from my session in a community server

Global chat should have been completely cleared, and not relaying from a community server while in singleplayer
