[O] Bug: MathJax rendering problem on Google Chrome [8.2.7c]

[Yi Wang]

The problem: I write a document with LaTeX equations in it, e.g.

    The quick $\alpha$ jumps over the lazy $\beta$

and use org-html-export-to-html to export to html. The equations are

rendered in MathJax. In Google Chrome (version 39 for me), the rending

time for the resulting html file is extremely slow (about 15 seconds).

I noticed that, if I replace the line in the html file

    <script type="text/_javascript_" src="" href="http://orgmode.org/mathjax/MathJax.js">http://orgmode.org/mathjax/MathJax.js"></script>

with

    <script type="text/_javascript_" src="" href="http://cdn.mathjax.org/mathjax/latest/MathJax.js">http://cdn.mathjax.org/mathjax/latest/MathJax.js"></script>

the rendering time becomes normal. I think it is related to a bug in

MathJax (report:

https://groups.google.com/forum/#!msg/mathjax-users/S5x-RQDPJrI/Tn31F4NjcTcJ),

and emacs is using an old verison. It would be great if the MathJax on

emacs server be upgraded or patched.
