Test the following code with MathJax:
<span title="<math>x^2</math>"><math>x^2</math></span>
[Q: Why should anyone put <math> inside a title attribute?
A: Some templates for citing books use micro-formats, so this
actually does happen.]
This is shown as
<spanclass="tex"dir="ltr">$x2$</span>
In PNG-mode the output looks correct.
Version: unspecified
Severity: normal
After Math extensions parser hook, the output becomes:
<span class="tex"><span class="tex" dir="ltr">$ x^2 $</span></span>
possibly there is some Tidy cleanup going on as well. This might 'work' with image mode, but such is pure accidental:
PNG mode:
<span class="tex"><img class="tex hide-images-handled" alt="x^2" src="//upload.wikimedia.org/math/c/6/6/c66452631491acdbf8e5ed69dfd19681.png"></span>
What about using $(node).text() instead of node.innerHTML in the ConvertMath function in modules/MathJax/extensions/wiki2jax.js? That way it should at least display correctly.
