MathML in Readium does not render some constructs correctly

[rkwright]

A MathML=enabled book submitted by Jean Kaplansky about another Readium issue, does not render correctly:

From Peter Krautzberger:
Thanks, Jean. I can reproduce it in Readium but not outside of it.

@Readium-devs does anyone have a build for the Chrome app that integrates MathJax 2.5 or 2.5.1?

[rkwright]

I don't believe we have done so yet.

@pkra provided useful info regarding the upgrade to MathJax v2.5, the build script "just" needs to be looked into:
#262

Let me know if you need anything else. On the one hand, it's obviously a MathJax bug on the other hand I can only reproduce this bug in Readium right now. So I'm hoping 2.5 or 2.5.1 will just make it disappear (silly hope, I know ;-) ).

BTW, my single-build repo has a build for 2.5 (I should update that to 2.5.1 though). So if someone could just grab that MathJax.js file and use it for a build of the chrome app (and send that to me) that'd be great.

FYI, I updated the build in my single-build repo to 2.5.1 (and updated the Grunt file -- I need to split MathJax.js programmatically on of these days, sigh..)

TODO: update this test report with latest MathJax 2.6 in develop branch:

Assuming the underlying MathML was something like

<math xmlns="http://www.w3.org/1998/Math/MathML">
  <mrow>
    <mo>(</mo>
    <mfrac>
      <mn>1</mn>
      <mn>2</mn>
    </mfrac>
    <mfrac>
      <mn>11</mn>
      <mn>2</mn>
    </mfrac>
    <mo>)</mo>
  </mrow>
</math>

then I can't reproduce this on the latest build.

I suggest we close this old issue, as there is no EPUB to test with (just a screenshot).
We have other EPUBs to test with (linear algebra, testsuite #100, etc.)
