4 years ago I think I finally figured it out. It displayed fine for me when I navigate there, but not when I followed your link. The difference is I navigated to http://www.clawpack.org/ruled_rectangles.html and your link uses https. Apparently there's a security thing with mathjax, but I fixed it by changing the mathjax link in conf.py to also use https.
The docs at https://www.clawpack.org/ruled_rectangles.html do not seem to be rendering at all. It looks like the tags are ok on a quick glance so I am not sure what is wrong.
