: Caption {#tbl-test}

Counter gets incremented

Because longtable is used by the first table

\begin{document}


\begin{longtable}[]{@{}ll@{}}
\toprule\noalign{}
a & b \\
\midrule\noalign{}
\endhead
\bottomrule\noalign{}
\endlastfoot
1 & 2 \\
\end{longtable}

\begin{longtable}[]{@{}ll@{}}
\caption{Caption}\label{tbl-test}\tabularnewline
\toprule\noalign{}
a & b \\
\midrule\noalign{}
\endfirsthead
\toprule\noalign{}
a & b \\
\midrule\noalign{}
\endhead
\bottomrule\noalign{}
\endlastfoot
1 & 2 \\
\end{longtable}




\end{document} 

It seems we missed something in our tests - the documents are compiling, but the counter fix is not working.

This could also be related to a change in LaTeX package - more complex to know.
