[NTG-context] Italic correction behaviour is odd

Dear list, why are italic corrections in the MWE below not inserted according to the rules stated in the new font manual? See comments in the code for details. I can reproduce the issue with TL2016 and latest beta. Cheers, Henri --- \definefontfeature [default] [default] [itlc=yes] \setupitaliccorrection[text] \enabletrackers[typesetters.italics] \starttext {\it beef} beer % seems to be fine {\it beef} \hbox{beer} % why is correction inserted here?
