rtd: text on images is unhelpful

[ulysses4ever]

I reach to Test Suite Fields docs and see:

I'd really love to copy and paste the exitcode stuff but I can't because it's a picture. Generally this page seems to overuse images. I propose we put copy-pasteable bits (words) in plain text, if possible.

I agree, even at the cost of making it less beautiful.

FWIW, when I right-click on the image, a context menu shows up, which allows me to use another renderer instead of SVG. If I choose one of the HTML renderers, I can select and copy the text. (I'm using Firefox.)

[kukimik]

This the line responsible for setting the SVG renderer as the default:

cabal/doc/conf.py

Line 106 in a260cde

mathjax_path = 'https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.5/latest.js?config=TeX-AMS-MML_SVG'

But it would be good to understand why the line was added (see 90b14ae), for which I don't have the time.

@kukimik thanks for investigating! I think we should try it:

• doc: render math with HTML to make it selectable (fix #8453) #9361
