How can I fix this duplication?

I've also been experiencing the same issue, upon investigation it seems that katex is being rendered twice, one as katex-mathml and the other as katex-html, from my observations katex-mathml is the correctly rendered one and I assume the one to keep.

Adding .katex-html { display: none; } does fix the issue, but some rendering issues still exist.. (does katex have mhchem? In my case \ce is not rendering correctly)

I'm fairly new to Katex and LaTeX so not sure on the best course of action
