I encountered a strange bug where
<span> was being used instead of
<a>. While viewing Could we please be a bit nicer to new users? which was linked in a new question recently posted, I noticed that I could not click on one of the names. Upon inspection of the html, I came across this:
I thought it was odd, and maybe that the user was deleted. However, I then noticed that all users which I had previously visited their profile had this same structure. Such as:
<span class="comment-user">Rob Cooper</span>
When inspecting users which I had not visited, the correct markup was shown.
<a href="/users/1337/brad-gilbert" title="7977 reputation" class="comment-user">Brad Gilbert</a>
I am not sure what causes this, and I do not see it on StackOverflow nor in normal Meta posts.
I cannot see names as links, for users who I have viewed their profile, in protected meta posts and/or community wiki posts.
I found this one as well which exhibited the same issue: Why aren't people voting for questions?
