Dear Hans Georg, this is indeed strange case. The main issue is that the contents of \sum command are missing tagging:
<munderover accentunder="false" accent="false"><mrow >∑ </mrow><mrow >i=1</mrow><mrow >n</mrow></munderover > It should be <munderover accentunder="false" accent="false"><mrow ><mo mathsize="big" >∑</mo> </mrow><mrow ><mi >i</mi><mo class="MathClass-rel">=</mo><mn>1</mn></mrow><mrow ><mi >n</mi></mrow></munderover > I think that issue is that it is contained in \mathop command. It seems to turn off the font processing. We should definitely take a look at this. The other issue is that Firefox renders the resulting document wrongly when I've added the missing markup by hand. It was fixed when I loaded MathJax for MathML rendering.
