That happens for version beta-0.79.1, but later versions have
correct behavior.

Interestingly (in beta-0.79.1), the X in
     $Y X\limits_{n=1}^\infty Z$
is treated just like it is in the correct code
     $Y \mathop{X}\limits_{n=1}^\infty Z$,
even to the point of shifting it vertically to center it on the
math axis and putting the same amount of space between it and the
surrounding symbols!

It almost seems like it was planned...;)
