[NTG-context] Two column itemize break grid layout

Hi, Grid layout gets broken if I use \startitemize[column,two]. \setuplayout[grid=on] \showgrid \starttext \input knuth \startitemize[packed] \item One \item Two \item Three \item Four \stopitemize \input knuth \startitemize[two,columns] \item One \item Two \item Three \item Four \stopitemize \input knuth \stoptext Is there a workaround?
