Wrong display of tblr inside longtblr

[dlobba]

While creating some complex tabular content nesting tblr inside longtblr I noticed that the first and last "hline" of the inner tblr are shown only for the last occurrence of tblr.

The following MWE (pdf here) reports exactly the problem I am experiencing: at line 3 and line 4 of the longtblr there are tblr nested. The last one (line 4) is displayed ok, while the one at line 3 is missing the first and last hline.

If removing line 4 of longtblr altogether, the tblr defined at line 3 is now displayed correctly.

\documentclass{article}

\usepackage{tabularray}

\begin{document}

\begin{tblr}[long]{rowfoot=1, rowhead=1, hlines, vlines, colspec={lX}}
    Head1 & Head2 \\                                % row 1
    1 & 2 \\                                        % row 2
    Some & %
    \begin{tblr}{hlines, vlines, colspec={lX}}
        Nested1 & Nested2 \\
        1 & 2 \\
        Some & %

        \\%
    \end{tblr}
    \\                                              % row 3 (not ok)
    Some & %
    \begin{tblr}{hlines, vlines, colspec={lX}}
        Nested3 & Nested4 \\
        1 & 2 \\
        Some & %

        \\%
    \end{tblr}
    \\                                              % row 4 (displayed ok)
\end{tblr}

\end{document}

Also note, if I was removing rowhead=1 and rowfoot=1 from longtblr options, I would experience the problem also on the last nested tblr.

To me this sounds like a bug as I would like to consider each tblr (and longtblr) environment as independent, while here what I can notice is that the behaviour of nested tblr is linked to the outermost environment.

Thank you for your attention and great work on this package!

Not reproducible with tabularray version 2023A (2023-03-01), both locally and using overleaf.com's texlive 2023. Which version of tabularray are you using?

[dlobba]

yep, that was it! I was using texlive from apt repository of a (quite) recent ubuntu Ubuntu 22.04.2 LTS and that was using tabularray 2021-12-01 v2021Q, which was kind of an old version.

Once I threw the ubuntu baked texlive away and installed texlive from TUG I got a newer version of the package and the problem was no more there.

Thanks for the support!
