Starting from a user's profile page, if you list all of their questions or all of their answers, posts whose titles contain complex MathJax formulae are not displayed properly.

There are some extreme examples, but I don't want to embarrass anybody else, so here is an example from the list of my own questions:

    $\begingroup$ Technically, it's an issue with the Activity page, not the Profile page. It's an old MathJax issue that was fixed years ago, but now it's back and much worse than before. $\endgroup$ Dec 17, 2021 at 18:25
  • $\begingroup$ @RandomVariable True. (There isn't a tag for the user activity page, though.) $\endgroup$ Dec 17, 2021 at 19:18

  • $\begingroup$ @TheSimpliFire Unfortunately it looks like this has not quite been completely stamped out - see the "reviewed edit" in this screenshot from today. Should I also report this somewhere else? $\endgroup$

  • $\begingroup$ @KReiser Interesting. I'm not exactly sure, you could post another answer in the meta thread (which is already extremely loaded so might not get much notice) or a Meta.SE question linking to the thread. $\endgroup$

  • $\begingroup$ @KReiser That seems to be an issue in the "All actions" tab of the "Activity" page. If I'm not mistaken, it is the same issue that has been reported by User Sycorax on Meta SE (see the "Update" added in revision 8, in particular), and that report is currently marked [status-planned]. $\endgroup$ Mar 8, 2022 at 9:14

    $\begingroup$ @TheAmplitwist excellent, thank you. $\endgroup$

  • $\begingroup$ As of today, MathJax is also not displaying correctly on the main Activity page. $\endgroup$ Mar 8, 2022 at 17:56

    $\begingroup$ @TheAmplitwist It's marked as "status-completed" here. $\endgroup$ Mar 8, 2022 at 18:26
  • $\begingroup$ @RandomVariable Oh, I see! This surely should get renewed attention, then. Perhaps another Meta SE post with the [regression] tag would be best...? $\endgroup$ Mar 8, 2022 at 18:36

    $\begingroup$ @TheAmplitwist I'm not sure what the best course of action would be, but I guess anything that attracts more attention to the problem would be good. I notified a MathJax developer (Davide Cervone) that the issue has returned. $\endgroup$ Mar 8, 2022 at 23:50
  • $\begingroup$ Another report recently added on Meta Stack Exchange: LaTeX formula have extraneous line breaks on the user profile page. $\endgroup$ Apr 16, 2022 at 6:22
