Today I've made my first contribution to MathJax in almost three years, adding the ability to specify a 'nonce' value for the stylesheets it creates, to comply with the site's Content Security Policy.
I've got an issue on the MathJax issue tracker explaining in a bit more detail: https://github.com/mathjax/MathJax/issues/2665
In particular, this makes MathJax work in mastodon again.
