pgfpages package incompatible

[mbertucci47]

The pgfpages package does odd things in tags and when uploaded to ngpdf. Here's an example:

\DocumentMetadata
  {
    lang=en-US,
    pdfversion=2.0,
    pdfstandard=ua-2,
    testphase={phase-III,math,title,table,firstaid}
  }
\documentclass{article}

\usepackage{pgfpages}
\pgfpagesuselayout{6 on 1}[a4paper,landscape,border shrink=5mm]

\title{pgfpages tagging test}

\begin{document}
First
\clearpage
Second
\clearpage
Third
\clearpage
Fourth
\clearpage
Fifth
\clearpage
Sixth
\clearpage
Seventh
\end{document}

The tags all show the word "First":

But if you click Content in Acrobat it looks more reasonable:

When you upload the pdf to ngpdf, the output is "First Second Third Fourth Fifth Sixth" seven times:

First Second Third Fourth Fifth Sixth

First Second Third Fourth Fifth Sixth

First Second Third Fourth Fifth Sixth

First Second Third Fourth Fifth Sixth

First Second Third Fourth Fifth Sixth

First Second Third Fourth Fifth Sixth

First Second Third Fourth Fifth Sixth

not sure what to make of that

Well tagging is wrong. With pdflatex the numbering of the container and their placement in the structure is okay, but they reference the wrong page object (a not existing page). With lualatex the page object is correct but the all containers have number 0 (as if all containers are on different pages). So this must be analysed.
