Steps to reproduce
- Open https://meta.wikimedia.org/wiki/User_talk:Tacsipacsi/test?dtenable=1 and look at the <h3> text.
Actual result
- It says Start a discussion with Tacsipacsi/test.
Expected result
- It says either Start a discussion with Tacsipacsi or Start a discussion about User:Tacsipacsi/test. There’s no user named Tacsipacsi/test. (And, by the way, I’d also expect that it’s not an <h3>, as there’s no <h2> level heading on the page. Either an <h2>, or a semantically meaningless <div>.)
