KaTeX headers are missing for documentation pages. #1092
Description
The KaTeX <link> and <style> headers seem to be missing in html files generated from mld files.
Example input mld file:
{0 Math}
Here is some math {m 4^{-10}}.
Generated html:
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml"><head><title>math (math)</title><meta charset="utf-8"/><link rel="stylesheet" href="odoc.css"/><meta name="generator" content="odoc 2.4.1"/><meta name="viewport" content="width=device-width,initial-scale=1.0"/><script src="highlight.pack.js"></script><script>hljs.initHighlightingOnLoad();</script></head><body class="odoc"><header class="odoc-preamble"><h1 id="math"><a href="#math" class="anchor"></a>Math</h1><p>Here is some math <code class="odoc-katex-math">4^{-10}</code>.</p></header><div class="odoc-content"></div></body></html>
(missing the katex js script & so on).
The KaTeX <link> and <style> headers are correctly present in documentation for the mli files in the same project.
I am using odoc 2.4.1.
