Loading amsmath after stix2 breaks \mapsto

[jfbu]

But the doc says it is recommended loading order.

% amsmath après stix2 alors \mapsto est cassé
\documentclass{article}
\usepackage[T1]{fontenc}
\usepackage{stix2}
\usepackage{amsmath}
\begin{document}
$\mapsto$
\end{document}

tested with recently updated TL2020, see log

% stix2 could add something like this, if this is the recommended 
% loading order
\AddToHook{package/after/amsmath}%
             {\def\mapsto{\DOTSB\mathchar"39AD }}

I noticed the same issue. For me, simply loading stix2 after amsmath fixed the problem.
