[NTG-context] Bug in maths environment: thematrix

[Otared Kavian]

Hi Hans,

I noticed that in some situations the command \thematrix does not show all its arguments correctly: some parts are omitted in the typeset formula. In some occasions adding some groupings solves the issue, but not always. I noticed this bug two weeks ago, but could not produce a minimal example until now…

Please see below, in particular the output for the matrices M_1, M_2 and M_3…

Best regards: Otared
