Hi I found stretching issue with integral symbol ∫.
Please find the following MathML markup for integral of some fractions. Here the height of the integral symbol does not stretches.
<math>

<mstyle displaystyle="true" largeop="true" stretchy="true">

</math>
When I use another symbol like {,[, or ( instead of ∫ is working fine and stretching is fine. But why stretching is not working for ∫
Please find the attachments.
Note:
1. I am using the latest MathJax version.( http://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-AMS-MML_HTMLorMML-full)
2. I am using latest chrome browser (Version 40.0.2214.115 m)
3. Also tested in Firefox and IE-11.
4. Searched on Google for the solution but no use.

I know this email exchange was from years ago, but I just happened to come across this and was wondering if there has been any update since then?
We are seeing stretchy single integrals, though they are quite straight/upright.
We're also seeing that the integral variants (e.g., double, triple, and bounded integrals) are not stretching.
