Recently, the TeX.SE question "\[\mu\] is printing the Greek letter mu on a separate single line" got onto the Hot Network Questions list.
Like many questions on TeX.SE, it contains some TeX markup in its title. Unfortunately, on sites that have MathJax enabled, this markup gets parsed and rendered as math:
I propose that either:
the entire Hot Network Questions sidebar should be excluded from MathJax parsing by styling it with the
at least, any hot questions from TeX.SE should be so excluded from MathJax parsing.
Or I suppose we could always implement this feature request, which asks for all questions with TeX in the title to be excluded from Hot Network Questions entirely. That might be throwing out the baby with the bathwater, though.
Ps. This issue is partially masked by another bug, which causes MathJax not to be rendered in many elements that are hidden by default and revealed using jQuery
.show(), such as all but the first five questions in the Hot Network Questions sidebar. The SOUP user script contains a generic fix for that bug, so users who have it installed will see this issue more frequently, but it occurs even without SOUP whenever a question with TeX markup in the title happens to show up among the top five hot questions that are always visible by default.
