Mathml render with matrix and power.
Hello.In advance, sorry if this kind of post has already been posted...
I'm currently working on a software thats generates mathml.
Thus, I'm trying to implement some features like matrix power.
I encountered a little problem with this kind of use.
The problem occurs when I use the mfenced tag in msup tag...
Example :
http://www.w3.org/Math/XSL/pmathml2.xml
This is an official test so, this is a good way to produce valid
mathml code and, it shows particulary well the display bug...
Jut compare the picture and the result.

System

Qt library

So, I just wanted to know if this is normal and if this will
be fix in the future version...
Thanks in advance.

It should work if you replace
with its equivalent
In MathML 2 they are the same because inferred 'mrow' around children of msub are implied. But Opera supports subset of MathML that does not infer mrows automatically. To avoid this limitation just wrap children in mrows explicitly in cases when layout schemata like msub and mfenced are nested.
<msup> <mfenced open="[" close="]"> <mrow> <mi>a</mi> <mo>+</mo> <mi>b</mi> </mrow> </mfenced> <mn>260</mn> </msup>
with its equivalent
<msup> <mrow> <mfenced open="[" close="]"> <mrow> <mi>a</mi> <mo>+</mo> <mi>b</mi> </mrow> </mfenced> </mrow> <mn>260</mn> </msup>
