I figured I would go check and it seems you're somewhat right, for newer messages (a few weeks) it does link me straight to the chat message so I can view the messages around it. Older messages from Ex. last year still have the behavior in the screenshot of the issue I linked - 'Go to message' simply takes me to a screen with only that message displayed and no others, with no way to actually get to that message in the chat. Obviously I don't have an easy way to tell yet if it's fixed for all messages going forward, or if it only works for recent messages, but either way it's some progress. Presumably in time I'll be able to tell.

So I donno, perhaps it's something funky with our Teams deployment, but this is such a basic feature that I have a hard time understanding how it could ever be implemented this way. Certainly no other chat service I've used has had this kind of problem.
