I would like to add that even Firefox/Gecko having one of the best support
for MathML around -- it is still not enough! Under certain situations even
if you feed MathJax certain MathML code it will revert back to HTML+CSS
depending on the Firefox version of the user... because it know the
shortcomings of the browser.

Frédéric Wang has worked intensively in fixing the MathML display bugs in
Gecko and WebKit, and when the masters fold his code in -- we will have a
nicer MathML level display in HTML engines. Anyone interested should check
his blog:

And the ones that don't are almost all using Adobe Digital Editions for
rendering engine - one of the worst out there! I am writing a paper "On
determining the HTML rendering engine of ePub readers" (based on what they
do wrong with CSS) and this was a big surprise for me. It looks like things
are changing and Kobo started to move away from ADE, but overall the
industry is moving very slowly.

The caveat being ... the support of SVG in browsers is roughly two years
ahead of support of SVG in ePub readers.
