some of the LaTeX is not rendered properly. Potentially wrong kind of MathJax?

This is the config I use:

  //Init MathJax
  MathJax.Hub.Config({
      tex2jax: {
          inlineMath: [ ['$','$'], ["\\(","\\)"] ],
          displayMath: [ ['$$','$$'], ["\\[","\\]"] ],
          processEscapes: true,
          processEnvironments: true
      },
      // Center justify equations in code and markdown cells. Elsewhere
      // we use CSS to left justify single line equations in code cells.
      displayAlign: 'center',
      "HTML-CSS": {
          availableFonts: [],
          imageFont: null,
          preferredFont: null,
          webFont: "STIX-Web",
          //styles: {'.MathJax_Display': {"margin": 0}},
          linebreaks: { automatic: true }
      }
  });
  MathJax.Hub.Configured();

I come from the future. We need to migrate some MathJax.
