Users with sufficiently high reputation have access to a "tools" page, which I like a lot. However, sometimes I find that the $\rm\TeX$ doesn't render properly. What is particularly puzzling is that sometimes some of the $\rm\TeX$ will render fine, but some of it will not. For example, in the screenshot below, note that in the upper left, $y^3 = x^4 + x+1$ renders fine, but elsewhere the raw $\rm\TeX$ is displayed. I am using Firefox 91.5 if that matters. At first I thought that maybe the browser was just taking a long time to process the MathJax, but the problem does not seem to resolve itself no matter how long I wait.
