Block mode not using moverunder

[cuppajoeman]

From what I understand when you use block mode in latex we do something like this:

\[
\sum_{i=1}^n i
\]

We would get :

when we try the same using latex2mathml we get the following:

@>>> convert(r"\sum_{i=1}^n i", display="block")
'<math xmlns="http://www.w3.org/1998/Math/MathML" display="block"><mrow><msubsup><mo>&#x02211;</mo><mrow><mi>i</mi><mo>&#x0003D;</mo><mn>1</mn></mrow><mi>n</mi></msubsup><mi>i</mi></mrow></math>'

I find this behavior strange because I requested it in block mode but I didn't get what latex gives when in block mode.
