fancyvrb's "samepage=true" keyword is ignored since fvextra v1.11.0

[akiyks]

MWE:

\documentclass{article}
\usepackage{fvextra}
\usepackage[english,latin,provide=*]{babel}
\usepackage{lipsum}

\begin{document}

\section{Intro}

\lipsum[1-4]

\lipsum[5][1-9]

\begin{Verbatim}[samepage=true,frame=single]
  [samepage=true]
  Short code
  Short code
  Short code
\end{Verbatim}

\lipsum[5][10-]

\lipsum[6]

\end{document}

With fvextra < 1.11.0, the verbatim block as a whole is pushed into page 2, which is the expected behavior.
With fvextra >= 1.11.0, the block is broken in the middle.

Bisection blames ac210ec as the first bad commit.

Can you please have a look into this?

This seems to work:

\makeatletter
\def\FV@bgcoloroverlap{%
  \ifx\FV@backgroundcolorboxoverlap\relax
  \else
    \nopagebreak  % <<< added
    \vspace{-\FV@backgroundcolorboxoverlap}%
  \fi}
\makeatother

Somehow the first use of \FV@bgcoloroverlap is in hmode while all following uses are in vmode, thus a simple \penalty\@M doesn't work for all cases.

@muzimuzhi Yes, your one-liner did the trick for me.

Thank you for taking the time!
