I think there’s a separate idiomatic autocomplete flow for what you’re trying to do. Try hitting “New Message”; typing your friend’s name; and selecting the result. The New Message window will transform into the existing-conversation window for that contact.
Not saying having it also work from search wouldn’t be good — but having this flow available is probably why the other issue hasn’t been fixed sooner.

I think this is how MS teams chat works too. It kind of makes sense, because it has a workflow for solving the "do you want your existing chat with Alice, or are you trying to start a new group chat with Alice & Bob" .
It does make sense if you're looking to send a new message. In my case, I'm typically doing a search so I can find information/photos from that thread. In this context, it's not so intuitive, and it never occurred to me to even try.
