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.
