Chat synchronisation makes keeping track of messages difficult

[Pennek]

Follow-up to #10540

Because osu!web and osu!lazer messages are synchronised, community members who have to interact with a large amount of people have to choose between cluttering their lazer chat to keep track of their messages and message-history, or closing in-game conversations to hopefully remember the names of the people they're expecting answers from.

I was hoping we could figure out some way to keep web-side chat history even after closing in-game tabs

They are intentionally in sync. If anything the UX for tabs will improve (and match the web implementation).
