Previously we would remove elements from the DOM, this caused Ember to
get extremely confused and blow up its rendering.
Instead only hide the element, do not remove it.
This commit ensures that wide equations can be scrolled on Safari. It previously failed because Safari doesn't not support the two value overflow shorthand.
* FEATURE: Add KaTeX in-browser rendering support.
* Remove ttf fonts from KaTeX
* Update KaTeX to v0.10.1, fix paths to fonts.
Font loading was fixed by rebuilding KaTeX
and specifiying absolute paths to fonts in CSS:
Steps to build KaTeX:
1. `git clone https://github.com/KaTeX/KaTeX.git && cd KaTeX`
`git submodule update --init --recursive`
2. Change paths to fonts:
`sed -ri 's/@font-folder.+$/@font-folder:
"\/plugins\/discourse-math\/katex\/fonts";/'
submodules/katex-fonts/fonts.less`
3. Disable TTF fonts:
`export USE_TTF=false`
Alternatively, we could modify `.browserslistrc` to match what
Discourse supports
3. Build KaTeX
`yarn && yarn builld`
4. Copy `katex.min.js` and `katex.min.css` from `dist/` to
`discourse-math/public/katex/`
5. Update fonts, copy woff and woff2 files from
`submodules/katex-fonts/fonts`
* Minor copy edit to settings
Mark MathKJax only settings
* Add Mhchem extension for KaTeX.
It is already automatically loaded for MathJaX.
