Sanitize (combined) MathJax configurations #330
Description
Originally reported at pkra/mathjax-node-page#42.
(Combined) configurations cause problems; we should sanitize them as they are not needed anyway.
Minimal example
var mj = require("mathjax-node"); mj.config({ MathJax: { config: ["TeX-AMS_SVG.js"] } }); mj.typeset({ math: 'E = mc^2', format: "TeX", svg:true, }, function (data) { if (!data.errors) {console.log(data.svg)} }); Results in
