Using \lstinline inside an \item in beamer class in case of incremental overlay specifications?

Question

The answers of Using \lstinline inside a \item work rather nicely with the beamer class.

But, as pointed out by the following MCEs when \beamerdefaultoverlayspecification{<+->} is uncommented, they don't work if incremental overlay specifications are used: the item labels are not printed.

Is there a way to use \lstinline inside a \item in beamer class in case of incremental overlay specifications?

  \documentclass{beamer}
  
  \usepackage{listings}
  
  \makeatletter
  \let\orig@item\item
  
  \def\item{%
      \@ifnextchar{[}%
          {\lstinline@item}%
          {\orig@item}%
  }
  
  \begingroup
  \catcode`\]=\active
  \gdef\lstinline@item[{%
      \setbox0\hbox\bgroup
          \catcode`\]=\active
          \let]\lstinline@item@end
  }
  \endgroup
  
  \def\lstinline@item@end{%
      \egroup
      \orig@item[\usebox0]%
  }
  \makeatother
  
  \begin{document}
  \begin{frame}[fragile]
    \frametitle{Foo}
  The arguments of the function are:
  
  % \beamerdefaultoverlayspecification{<+->}
  \begin{description}
  \item[\lstinline!foo!]
      Name of the file \\[1cm] % other [ ] still work as normal!
      something
  \item[\lstinline!bar!]
  Permissions
  \item[\lstinline!%^$]_!]
  verbatim
  \end{description}
  \end{frame}
  \end{document}

  \documentclass{beamer}
  
  \usepackage{listings}
  
  \newcommand*{\lstitem}[1]{
    \setbox0\hbox{\lstinline{#1}}
    \item[\usebox0]
  }
  
  \begin{document}
  \begin{frame}[fragile]
    \frametitle{Foo}
    The arguments of the function are:
  
    % \beamerdefaultoverlayspecification{<+->}
    \begin{description}
      \lstitem{foo}
      Name of the file
      \\[1cm] % other [ ] still work as normal!

    \lstitem{bar}  Permissions
