Missing math formatting in documentation pages

[gadmm]

The following page uses the math feature of odoc backed by katex: https://ocaml.org/p/memprof-limits/0.2.1/doc/statistical.html. As you might see, the maths aren't currently displayed.

Depending on your odoc version this might be related to https://github.com/ocaml/odoc/issues/1092
