Direct tex2svg example rendering as blank when I paste into HTML file

I'm trying to run the tex2svg example and finding that it renders as a blank page when I try to paste it into an HTML file. I'm trying to paste the CSS and SVG output respectively into an HTML page skeleton like this:

<html>
    <head>
        <style>
        --css output...
        </style>
    </head>

    <body>
        <mjx-container> ... </mjx-container>
    </body>
</html>

A full Gist with this HTML file is here.

Am I misunderstanding how this is supposed to work? I tried the same thing with the tex2chtml example and it worked so I'm wondering what I'm missing with tex2svg.

This is caused by the problem discussed in mathjax/MathJax-src#365 and fixed in mathjax/MathJax-src#417, which is that the xlink namespace is being mishandled, and you are getting xlink:xlink:href for the references in <use> elements. These should be xlink:href instead, so one solution would be to use a regular expression to replace xlink:xlink:href with xlink:href. Alternatively, you could prevent the use of font caching (at the expense of space) by setting fontCache: 'none' in the svg block of your MathJax configuration. E.g.

MathJax = {
  svg: {
    fontCache: 'none'
  }
}

The problem with be fixed in the next release, but either solution would handle things until then.
