[NTG-context] Inline math with \int and \sum exhibits nonstandard behaviour

To me the following two MWEs look pretty much the same:

\setupbodyfont[10pt] % same font size as LaTeX
\starttext
$\sum_{k=1}^{n} a_k$
\startformula
\sum\nolimits_{k=1}^{n} a_k
\stopformula
\stoptext


\documentclass{article}
\begin{document}
$\sum_{k=1}^{n} a_k$
\[
\sum\nolimits_{k=1}^{n} a_k
\]
\end{document} 

I tried that with versions of ConTeXt from TeX Live 2016, 2017, 2018, and 2019,
as well as the latest beta, all with the same result.

You refer to ma-cb-en page 19, but which of the two equations, the first or the
second one?  Keep in mind that the first one uses

    \sum_{n=1}_^{m}

where you are using

    \sum\nolimits_{k=1}^{n}

Cheers, Henri
