When I checked the source code I saw that the anchor tag was being applied
to the profile image, so I assumed that the link should be clickable only
inside the area of the profile image.

Yes, I was referring to a small area around the hovercard which was clickable. Not a big issue, but just something I noticed the other day. 😄

I've seen the same issue (on latest stable install).

Is there any way to sort Differential diffs by how simple the change is? Is there a tag for small bug fixes so newbs can come in and see how a small problem was fixed?

Thanks!

Poking around the source code was fun. Please find time to put up minor issues like these for newbs. Thanks :)

Is it in PhabricatorFeedStory or PhabricatorFeedBuilder from the folder src/applications/feed. If I'm looking in the wrong place, could you please clarify what you meant as "level or two up".

I just noticed this task as a beginner task. Shall I try to fix this?
