I recently came across this answer, which involved some pretty precise calculations. Here's how it rendered in my browser*:
Two questions arise:
- What is the desired technical behavior? Should the MathJax there really cut off the sidebar?
- What is the desired community behavior? Should users post MathJax this long?
For what it's worth, adding
overflow-x: hidden to the
div.post-text truncates the output as expected.
