joplin-renderer/assets/katex/katex.css should be updated according to KaTeX 0.12.0.

[spencer246]

Environment

Joplin version: v1.0.234
Platform: Windows, but relevant to any platforms
OS specifics:

Steps to reproduce

1. Fresh install Joplin v1.0.234 or v1.0.235.
2. Make sure that KaTeX plugin is enabled.
3. $a$ is rendered as an upright font, not italic.

---

Describe what you expected to happen

As in v1.0.233, $a$ should be properly rendered as italic.

How to fix

Since this commit, KaTeX has been upgraded from v0.11.0 to v0.12.0.

KaTeX has changed the name of a span class span.mathdefault to span.mathnormal. For example, while KaTeX v0.11.0 renders LaTeX syntax $a$ to HTML <span class="mord mathdefault">a</span>, KaTeX v0.12.0 renders $a$ to $<span class="mord mathnormal">a</span>$.

Joplin uses katex.css in joplin-renderer/assets/katex/katex.css instead of the CSS file downloaded by npm to node_modules. Therefore, joplin-renderer/assets/katex/katex.css should be manually updated to https://cdn.jsdelivr.net/npm/katex@0.12.0/dist/katex.min.css.

Yes, this is correct. I've noticed this as well, when testing/adding a newer Mermaid version.
I'm still waiting for Laurent's answer in the forum, otherwise I would have already commited the new assets (including the katex ones).
