Bug ID: 66572
Summary: MathJax generates table markup with incorrect
displaystyle
Product: MediaWiki extensions
Version: master
Hardware: All
OS: All
Status: NEW
Severity: normal
Priority: Unprioritized
Component: Math
Assignee: wikibugs-l@lists.wikimedia.org
Reporter: fred.w...@free.fr
CC: peter.krautzber...@mathjax.org, phy...@ckurs.de

MathJax currently interprets the default value for displaystyle on mtable as
"inherited" instead of the value "false" specified in the MathML spec. The
problem is that this affect the generated MathML output. For example for the
markup
{\displaystyle {\begin{aligned}\Gamma (z)&=\int
_{0}^{x}e^{{-t}}t^{{z-1}}\,{\frac {{\mathrm {d}}t}{t}}+\int
_{x}^{\infty }e^{{-t}}t^{{z+1}}\,{\frac {{\mathrm
{d}}t}{t}}\\&=x^{z}e^{{-x}}\sum _{{n=0}}^{\infty }{\frac
{x^{n}}{z(z+1)\cdots (z+n)}}+\int _{x}^{\infty }e^{{-t}}t^{{z}}\,{\frac
{{\mathrm {d}}t}{t}}.\end{aligned}}
on the Fourier Transform page, Mathoid generates <mtable> without explicit
displaystyle="true" attribute and so the content render incorrectly in Gecko 29
and (I guess) MathPlayer.

An issue is opened in MathJax:
https://github.com/mathjax/MathJax/issues/839
We should cherry-pick the fix when it is ready before Math 2.0.
