Hi everyone.
The following example works in ConTeXt MkIV but fails in ConTeXt LMTX:


\def\rgeq{\vcenter{\rotate[rotation=270]{$>$}}}

\definemathmatrix[void][left=,right=,simplecommand=voidmatrix]

\starttext

\startformula

\voidmatrix{%

G_{1,1}, >, G_{1,2}, >, G_{1,3}, >, G_{1,4}, \ldots, G_1;

\rgeq , , \rgeq , , \rgeq , , \rgeq , , \rgeq;

G_{2,1}, >, G_{2,2}, >, G_{2,3}, >, G_{2,4}, \ldots, G_2;

\rgeq , , \rgeq , , \rgeq , , \rgeq , , \rgeq;

G_{3,1}, >, G_{3,2}, >, G_{3,3}, >, G_{3,4}, \ldots, G_3;

, , , , , , , , \rgeq

}

\stopformula

\stoptext

In LMTX only the first column of rotated symbols appear. My ConTeXt version
is:

LuaTeX 2.08 20201103 + ConTeXt MkIV 2020.11.13 19:13

Thank you very much.

Best regards,

Jairo :)
