I have noticed, several times already, that some titles containing MathJax are rendered incorrectly in review queues, i.e. across multiple rows. I can't remember for sure, but I expect this to also happen on MathOverflow. The same titles display just fine in the "Stats" and "History" tabs of the review queues, on the main page and, of course, when the page containing the question is opened. I can also guarantee that the MathJax was error-free and basic in each case. Below is one such example. I believe that this is a bug; if the moderators share my opinion, I would appreciate if they forwarded this to the SE staff (MSE community managers).

(I am using the HTML-CSS renderer with Firefox 92 for Windows 10, I haven't tried with other renderers or browsers.)
