Going to a user's page by clicking on their name in the PM page

I noticed that when you get a private message from someone, you can't actually go to their page by clicking on their name. It's highlighted as if it is a link, but you can't interact with it. This feels very counter-intuitive and limiting.

I noticed there are some threads about going to people's pages by clicking on their names (in your notifications, for example) and I think this fits in with those suggestions.
