sectioning commands reset para-tag to default

[u-fischer]

As Hn-tags do not allow P as child, the sectioning commands change the paratag and reset it later to the default (text-unit).

This is perhaps not the wanted behaviour if someone generally changes the paratag:

\DocumentMetadata{uncompress,testphase=phase-III}
\documentclass{article}

\begin{document}
\tagpdfsetup{add-new-tag=paragraph/P,paratag=paragraph}

some text

\section{section}

some text
\end{document}
