siunitx using wrong \mathrm with eulervm and mathpazo

Question

By loading both mathpazo and eulervm, the units are written in the euler mathfont when using siunitx and not in upright roman font. Even if it's explicitly set in sisetup :

unit-math-rm=\mathrm

I'm using Mac TexLive 2016, all packages updated. When \mathrm is used regularly in math mode, it works as expected. So there must be some issue how siunitx uses \mathrm.

MWE:

\documentclass{article}
\usepackage{mathpazo}
%commenting eulervm out prints units right again
\usepackage[euler-digits]{eulervm}
\usepackage{siunitx}

\begin{document}
\SI{5}{m/s}
\end{document}

as opposed to

Answer 1

This is 'by design': eulervm sets up letters in \mathnormal which are very different from \mathrm, so siunitx does

\sisetup{math-rm = \mathnormal}

at the start of the document unless the user has changed it from the standard value of \mathrm. You can override this at the start of the document:

\documentclass{article}
\usepackage{siunitx}
\usepackage{eulervm}
\AtBeginDocument{\sisetup{math-rm = \mathrm}}
\begin{document}
\SI{5}{m/s} $5\nobreak\,\mathrm{m}/\mathrm{s}$
\end{document}
