[NTG-context] More funny numbers

Hi everyone! The following example shows that numerators of fractions inside math alignment environments appear with a funny size: \startTEXpage \startformula \startmathalignment[n=1,align=middle] \NC \frac{1351}{780}>\sqrt{3}>\frac{265}{153}, 3013 \frac{3}{4}>\sqrt{9082321}, \quad 1838 \frac{9}{17}>\sqrt{3380929} \NR \NC 1009 \frac{1}{6}>\sqrt{1018405}, \quad 2017 \frac{1}{4}>\sqrt{4069284} \frac{1}{38}, \quad 591 \frac{1}{8}<\sqrt{349450} \NR \NC 1172 \frac{1}{8}<\sqrt{1373943\frac{84}{33}}, 2339 \frac{1}{4}<\sqrt{5472132 \frac{1}{16}} \NR \stopmathalignment \stopformula \stopTEXpage It's actually nice to find those bugs when one makes heavy use of math environments. For comparison, LuaTeX prints the correct output. Jairo :)
