esp. in a header; see screenshot.
The first sentence is hyperlinked; the second (starting with "Look") isn't.

Hi @nlharris ! I'd like to work on this issue if we still have it.

@ShwetKhatri2001 I've just had a look at that old PR and it doesn't fix the issue, so if you can pick it up that would be great!
