Hi,

I try to use the Noto Sans Math fnt which can be downloaded from
https://fonts.google.com/noto/specimen/Noto+Sans+Math

But I use it like the following

\definefontfamily[myfonts][rm][latin modern roman]
\definefontfamily[myfonts][mm][noto sans math]
\setupbodyfont[myfonts,rm,12pt]
\starttext
Test Noto Sasn Math Fonts
\startformula
a^2 \quad \sqrt{a}
\stopformula
\stoptext

I get the errors `Math error: parameter 'supshiftup' with id 51 in style 0
is not set'.

Is there some method to solve it?
