strc-mat.mkiv (I’m not sure if the first change after \dorecurse is correct)

   \normalexpanded{\scratchtoks{\the\scratchtoks\the\c_math_align_c}}}

\def\math_alignment_NR_indeed[#1][#2]%
- {\donestedformulanumber{#1}{#2}% to be tagged (better an attribute)
+ {\strc_formulas_place_number_nested{#1}{#2}% to be tagged (better an attribute)
   \crcr
   \dostoptagged % finish row
   \noalign{\glet\math_alignment_NC\math_alignment_NC_first}} % noalign used for change state, conditional does not work here

\def\math_align_NR_generic[#1][#2]%
- {\donestedformulanumber{#1}{#2}\crcr}
