The Accessible.js config loads accessibility-menu extension which in turn loads mathjax-sre.js library. There is a bug in this library https://github.com/zorkow/speech-rule-engine/issues/182 that makes it fail in RequireJS environments. This has been reported upstream as https://github.com/mathjax/MathJax/issues/1854 As an immediate solution for now, this patch changes the default MathJax configuration so that it does not load accessibility extensions at all.
