Every question seems to be associated with a chat room, and that's fine. The problem is that, coming upon a chatroom associated with a question, it's not clear how to find the question without resorting to either memory or brute force.
This is a question of mine on TopTex: https://topanswers.xyz/tex?q=2877
I got a notification for a reply to one of my messages in the chat associated with that question. However, the notification (and the email message) points to the chat room, with no reference to the question itself!
When one is located at the chat room, there's no obvious link to the associated question: https://topanswers.xyz/tex?room=2923
In particular, the comments on answers are supposed to link back to the answers, but the link is instead broken, because it's local to the page. It points to https://topanswers.xyz/tex?room=2923#a2984 instead of to https://topanswers.xyz/tex?q=2877#a2984.
