That is to be expected, as the document is not expected to be saved as 
rendered, but as it was.  Furthermore, there is no reliable method to remove 
all SCRIPT element nodes from a document tree once they are not needed 
anymore.

That would be suboptimal, indeed.  MathJax should use CSS classes, which 
would reduce the footprint considerably.
