an alternative to using these mfrac linethickness="0" 'tricks' is to use
a nested munder:

<m:math>
  <m:mstyle displaystyle="true">
    <m:mrow>
      <m:munder>
        <m:munder>
          <m:mo>&prod;</m:mo>
          <m:mrow><m:mi>i</m:mi><m:mo>=</m:mo><m:mn>2</m:mn></m:mrow>
        </m:munder>
        <m:mrow><m:mi>i</m:mi><m:mo>&#x2260;</m:mo><m:mi>t</m:mi></m:mrow>
      </m:munder>
    </m:mrow>
  </m:mstyle>
</m:math>

though (in mozilla) the prod symbol is now much larger, I am sure though
that there are attributes to control the size.
