si.tex test raises errors under pdflatex? #1734
Description
I'm assuming this is some texlive 2021 regression.
cd t/complex ; pdflatex si.tex
produces a number of "invalid number" errors, with my:
(/usr/local/texlive/2021/texmf-dist/tex/latex/siunitx/siunitx.sty
Package: siunitx 2021-11-03 v3.0.35 A comprehensive (SI) units package
for example
! Package siunitx Error: Invalid number '\pi '.
For immediate help type H <return>.
...
l.60 \num{\pi}
unsure what the implications are to the latexml binding yet, but thought I'd record the pdflatex problem already.
