2012 and had the impression that this either shouldn't happen or
that the behaviour could at least could be changed with

But in my examples \setupmathematics[italics=...] doesn't do
anything. Every line looks looks identical to me (the second example
is from the header of xits-math.lfg). Is this behaviour expected? If
yes, what should one do to get an italic correction is such cases?

hm, seems that i messed up a pointer ... i'll fix it ...
