[NTG-context] huge parentheses with xits

Hi! The following works well with default font but produces too small parentheses with xits. \doifmodeelse{xits}{\setupbodyfont[xits]} \starttext \startformula \left( \startmatrix[n=1]\dorecurse{10}{\NC 1\NR}\NC 1\NR\stopmatrix \right) \stopformula \stoptext Any ideas?
