Some integral signs on M.SE are not rendering correctly for me. I've been having this problem for at least a few months, and it persists when I refresh the page. The problem is rare but frequent enough that it's annoying.
As you can see, the top part of the integral sign is cut off. This is a screenshot of a section of this answer. I have also had this happen on questions and answers I have posted.
Has anyone else experienced this problem? What should I do about it?
I'm on the most recent version of Safari.
Edit: Following the advice of Martin Sleziak, I tried to replicate this bug in the non-default renderers (SVG and MathML). They both render integrals correctly. I conclude that this is a problem with the HTML-CSS renderer.
