Baseline of tblr array

[rtoi]

I have tried to understand how baseline setting of tabularray-arrays works. After many experiments it seems to me that the baseline setting does not have an effect unless there is hlines setting in inner specifications.

This example was tested with tabularray versions 2022A and 2021. The idea is to treat text inside a table as one cell. That's the reason to use \\\end{tblr} instead of \end{tblr}.

\documentclass{article}
\usepackage{tabularray}
\begin{document}

\subsection*{tblr without hlines}
baseline=b \begin{tblr}[b]{c}{r1\\r2\\r3}\\\end{tblr} 
baseline=t \begin{tblr}[t]{c}{r1\\r2\\r3}\\\end{tblr} 
baseline=m \begin{tblr}[m]{c}{r1\\r2\\r3}\\\end{tblr}

\subsection*{tblr with hlines}
baseline=b \begin{tblr}[b]{hlines}{r1\\r2\\r3}\\\end{tblr} 
baseline=t \begin{tblr}[t]{hlines}{r1\\r2\\r3}\\\end{tblr}
baseline=m \begin{tblr}[m]{hlines}{r1\\r2\\r3}\\\end{tblr}
	
\end{document}

Have I missed something?

Clearly I had missed virtual alignment setting inside a cell... After changing the example to what follows, the result is just what I was after in the first place

\documentclass{article}
\usepackage{tabularray}
\begin{document}
  \subsection*{tblr without hlines}
  baseline=b \begin{tblr}[b]{Q[c,b]}{r1\\r2\\r3}\\\end{tblr} 
  baseline=t \begin{tblr}[t]{Q[c,t]}{r1\\r2\\r3}\\\end{tblr} 
  baseline=m \begin{tblr}[m]{Q[c,m]}{r1\\r2\\r3}\\\end{tblr}
\end{document}

Problem solved.
