Thanks for the report. This is due to commit dc0c2f7 that was to prevent the SVG stylesheet from being updated unnecessarily. But it also disabled the MathJax.svgStylesheet() function after it is called once or the initial typesetting occurs.

If you disable the initial typesetting (by setting MathJax.startup.typeset to false in your configuration, that should let you call Mathjax.svgStylesheet(). Alternatively, you could set MathJax.startup.document.outputJax.svgStyles = null before calling it. Or you could just use MathJax.startup.document.outputJax.svgStyles itself, which will point to the actual stylesheet in use.
