protrusion of the soft hyphen

[u-fischer]

Description

The tagging code replaces with luatex hyphens from hyphenation by soft hyphens. This disables the protrusion of these hyphens.

It would be nice if microtype could add for open type fonts also protrusion values for the softhyphen.

Minimal example demonstrating the issue

\DocumentMetadata{tagging=on}
\documentclass{article}
\usepackage[ngerman]{babel}
\usepackage{kantlipsum}
\usepackage{microtype}
\textwidth=5cm

%\LoadMicrotypeFile{LatinModernRoman}
%\SetProtrusion[load=LMR-default]
%  {encoding =TU,family= Latin Modern Roman } 
%  {"AD= {400,500}}

\begin{document}
%no protrusion
\kant[1][1]

\tagpdfsetup{activate/softhyphen=false}
%protrusion
\kant[1][1]
\end{document}
