Dear John,

Sorry, I should have tested more extensively. You are correct, this does 
fix the LaTeX to Word conversion. However, we are actually converting 
MathML to Word. When I originally reported it I got the same incorrect 
result on conversion from LaTeX to Word and on conversion from MathML to 
Word so I reported both at once as I assumed, obviously incorrectly that 
the two issues had the same cause. I have now checked everything and the 
situation is:

LaTeX to Word is now producing the correct output
MathML to Word is still producing incorrect output

The MathML is:

<math xmlns="http://www.w3.org/1998/Math/MathML" display="block">
  <mrow>
    <munder>
      <mrow>
    <munder>
      <mrow>
        <mi>x</mi>
        <mi>x</mi>
        <mi>x</mi>
        <mo>&#x2026;</mo>
        <mi>x</mi>
        <mi>x</mi>
      </mrow>
      <mo>&#xFE38;</mo>
    </munder>
      </mrow>
      <mrow>
    <mi>n</mi>
      </mrow>
    </munder>
  </mrow>
</math>

The above renders correctly in Firefox (native rendering) and using 
MathJax. I am pretty sure that this is the right MathML?

I attach a screenshot of what I get when I render the above and the output 
of the transform to Word. I'll keep trying to work out what is actually 
happening.

Many thanks for any insights,
Emma
