• [x ] Confirmed that it can be reproduced in built-in themes without customized css.

  If it only exists in 3rd party themes or css, you can still report it, but please attach the theme target or the css file. We may not "fix" it, if it is caused by 3rd party themes or css styles that we cannot support.

Is is same with https://www.mathjax.org/#demo

\end{array}
