I recently asked a question on serverFault. This is the normal link, whereas the second one is the one I got via notifications, leading to a comment.
The commands seems to have been removed by a moderator, at least I guess that's what happened. Clicking the second one leads to a very minor CSS bug, at least it does for me: the dotted line for comments is visible:
It seems like the element with id
comments-QUESTION_ID is missing the
dno class, with seems to be normally applied when there a now comments present.
