1Dot yes the discussion we merged into this one is called "Websocket extension issue on profile discussion page.", the change you made an image of holds that same title, because that event was merged along as well. But that event belonged to a different discussion than the one we are currently viewing. The event should probably be deleted as it has no immediate relation to the current discussion.
Please this does not relate to the websocket bug this discussion is about, in fact it is not a real bug at all. It's a side effect of the merge extension and honestly it's not bad because it guarantees a complete history.
