[NTG-context] Keep framed on the baseline

All, I have: \placeformula[-] \startformula \eqalign{ &\text{Divisors of 12}: \framed{1},\ \framed{2},\ \framed{3},\ 4,\ \framed{6},\ 12\cr &\text{Divisors of 18}: \framed{1},\ \framed{2},\ \framed{3},\ \framed{6},\ 9,\ 18} \stopformula But I'd like to keep the numbers on the same baseline and let the frame dip below the baseline.
