It can be fixed with a strut option for lists, e.g.
\setuplist[strut=no]. The problem in this case is that the ex-height for
the italic font is larger than the ex-height for the upright font which
pushes the text down because add a strut at the begin and end of the
entries.
Below is a minimal example of the problem, the \setstrut setting changes
the height of the strut for the italic font.
%%%% begin example
\showstruts
\setupbodyfont[pagella]
\starttext
\dontleavehmode\it
\ruledhbox{\strut Section}
\ruledhbox{\setstrut\strut Section}
\stoptext
%%%% end example
Most fonts (I checked only a small number) don't have such a big
difference between the ex-height of the upright and italic styles which
makes it hard to notice the problem.
%%%% begin example
\define[1]\ShowExheight
{\bgroup
\setupbodyfont[#1]
\subject{#1}
\starttabulate
\NC tf \NC \tf \the\exheight \NC\NR
\NC it \NC \it \the\exheight \NC\NR
\NC bf \NC \bf \the\exheight \NC\NR
\NC bi \NC \bi \the\exheight \NC\NR
\stoptabulate
\egroup}
\starttext
\ShowExheight{pagella}
\ShowExheight{modern}
\ShowExheight{dejavu}
\ShowExheight{termes}
\stoptext
%%%% end example
