Bug with Doubly-Subscript Equations between Remark/KaTeX

[ebridge2]

I could be wrong, but I think this is a remark-related issue. See the attached sandbox, which reproduces the issue. On the first slide, you can see that the equation is formatted correctly. However, when I add too many multiple-subscript items such as the second slide, it seems like remark has issues handling this situation. The LaTeX code is valid.

Hi @ebridge2

It should work if you escape the underscores (see below) on the second slide. This is a known remark problem. See #645 for details.

$$f\_{xz}(x) f\_{xz}(x)$$
