In general mathjax and jekyll work together just fine, but I have this one equation that doesn’t want to render and I suspect it has to do with jekyll. The following minimal html file (opened in the browser, without involving jekyll) renders the equation correctly:

```
<html><body>
<script id="MathJax-script" async src="https://cdn.jsdelivr.net/npm/mathjax@3/es5/tex-mml-chtml.js"></script>
\begin{equation}
(A)'_{i,j} = A_{j,i}
\end{equation}
```

But the following minimal index.md file, in an otherwise empty directory, served with `jekyll s`

, doesn’t render the same equation and only shows the latex source code instead:

```

<script id="MathJax-script" async src="https://cdn.jsdelivr.net/npm/mathjax@3/es5/tex-mml-chtml.js"></script>
\begin{equation}
(A)'_{i,j} = A_{j,i}
\end{equation}
```

Can anyone reproduce this issue? If so, any ideas how to resolve this? I think it has to do with the parentheses or the apostrophe, because the equation `A_{i,j} = A_{j,i}`

is rendered correctly.
