On my Chrome browser in Windows 10, whenever a question that has MathJax is edited the MathJax no longer renders and is shown as, for example,
$q$ instead of $q$. This seems to persist until I refresh the page. I'm sure this is not intended behavior, but it also seems that I can't possibly be the only one to see this so I would find it hard to believe that it isn't a known issue.
Last time I used my desktop computer to go on MSE was over a month ago, and I don't think this issue was present then.
I'm using Chrome version 77.0.3865.120. LeBlanc was kind enough to give a link to the same issue Mathjax stops rendering after clicking "An edit has been made to this post". The only thing that's different is the browser.
