colortbl breaks header tagging in tables

[u-fischer]

\DocumentMetadata{
  testphase={phase-III,table}
  }
\documentclass{article}
\usepackage{colortbl}

\begin{document}
\tagpdfsetup{table/header-rows={1}} % set header
\begin{tabular}{ll}
a & b\\
b & c
\end{tabular}
\end{document}

Without colortbl the first row of the table is tagged as TH, with colortbl all cells are TD. The problem is that colortbl overwrites the \endarray definition with the finalizing code. This seems to work:

\DocumentMetadata{
  testphase={phase-III,table}
  }
\documentclass{article}
\usepackage{colortbl}
\makeatletter
\ExplSyntaxOn
% \endarray definition from new array sty.
\def\endarray {
  \tbl_crcr:n{endarray} \egroup
  \UseTaggingSocket{tbl/finalize}
  \tbl_restore_outer_cell_data:
  \egroup
  \@arrayright \gdef\@preamble{}%
  \CT@end %added
}
\ExplSyntaxOff

\begin{document}
\tagpdfsetup{table/header-rows={1}} % set header
\begin{tabular}{ll}
a & b\\
b & c
\end{tabular}
\end{document}
