Solution to Plotly Issue #3828 for the new version of Kaleido

[konmenel]

A while ago I implemented a fix for the same issue in PR #168. However, I saw that Kaleido had some major updates and it no longer needs to be compiled with Chromium. I suspected that the fix would be even easier with the new code so I had a look.

The change is 1 line which adds a script tag in the HTML to configure the stroke in Mathjax. This is hardcoded which might not be ideal, but it is very easy to move the config in a separate file if need be (something like what I did in the old RP).

Hopefully, this will close Plotly's issue 196

Issues that I encountered

While I was testing I noticed two issues which I list below:

1. Chrome headless was not loading similar to issue Image export fails #241. I already posted my solution in the discussion of the issue.
2. Two pages appear in the pdf, issue Two pages appear in pdf output #235. I haven't investigated but one solution which is not ideal is to generate an SVG instead. Converting from SVG to PDF is very simple.

Note

I use Arch btw

Yeah, this looks good. We have some wide changes coming in so I may have to integrate it manually. Thanks for doing this @konmenel
