On a table in a crossref div, attributes remain untouched. It's a
backwards compatibility thing.

\begin{longtable}[]{@{}ll@{}}
\caption{\label{tbl:table1}table}\tabularnewline
\toprule\noalign{}
foo & bar \\
\midrule\noalign{}
\endfirsthead
\toprule\noalign{}
foo & bar \\
\midrule\noalign{}
\endhead
\bottomrule\noalign{}
\endlastfoot
1 & 10 \\
2 & 20 \\
3 & 30 \\
\end{longtable}

However, if a table in a crossref div has id set, then its id takes
precedence in LaTeX.

\begin{longtable}[]{@{}ll@{}}
\caption{table}\label{quux}\tabularnewline
\toprule\noalign{}
foo & bar \\
\midrule\noalign{}
\endfirsthead
\toprule\noalign{}
foo & bar \\
\midrule\noalign{}
\endhead
\bottomrule\noalign{}
\endlastfoot
1 & 10 \\
2 & 20 \\
3 & 30 \\
\end{longtable}

Even if attributes are empty

\begin{longtable}[]{@{}ll@{}}
\caption{\label{tbl:table2}table (no attributes)}\tabularnewline
\toprule\noalign{}
foo & bar \\
\midrule\noalign{}
\endfirsthead
\toprule\noalign{}
foo & bar \\
\midrule\noalign{}
\endhead
\bottomrule\noalign{}
\endlastfoot
1 & 10 \\
2 & 20 \\
3 & 30 \\
\end{longtable}

But tables without a div don't get wrapped since Pandoc 3.8.2:

\begin{longtable}[]{@{}ll@{}}
\caption{table (crossref id)}\label{tbl:table3}\tabularnewline
\toprule\noalign{}
foo & bar \\
\midrule\noalign{}
\endfirsthead
\toprule\noalign{}
foo & bar \\
\midrule\noalign{}
\endhead
\bottomrule\noalign{}
\endlastfoot
1 & 10 \\
2 & 20 \\
3 & 30 \\
\end{longtable}
