Katex duplicates text

[MurelloS]

I used the library 3 weeks ago, and it worked very well.
I started refactoring, updated libraries, and there was a problem.
Katex parameters are duplicated as text.

<span class="katex">
    <span class="katex-mathml"></span>
    <span class="katex-html" aria-hidden="true"></span>
</span>

it turns out that something like this ABCABC

This effect most likely occurs because of missing / invalid css styles. Please ensure to have access to

  <link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/katex/dist/katex.min.css">
  <link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/markdown-it-texmath/css/texmath.min.css">

or their local (full) counterparts.
