Tabsrmm + IRC: leave chat room for server window

[JeanPaulLucien]

Open anything in Tabsrmm;
Open Server window for any IRC account;
Press RMB on Server window tab;
Press LMB on Leave chat room.

Expected behavior

I do not know. We can open Server window even for offline accounts it's okay, because we watch a server messages. I suppose there is not action "Leave" for this tab as for channels so I suggest to make not active Leave chat room for Server window tabs.

Actual behavior

Nothing goes.

Does it work in stable version?

I do not know.
