MathJax highlight stopped

I just loaded version 0.16 and there is no mathjax syntax highlighting anymore. I tried both the default theme and the (updated) Minimal theme. It’s much harder to read this way.

Please resubmit this bug report and make sure that: 1) you follow the bug report template, 2) you use the default theme (no css) and 3) there are no third-party plugins enabled (You can use the sandbox vault for 2 and 3).
