spurious indent combining standalone, french, itemize and verbatim

Question

I have an indentation problem that I finally solved adding \usepackage{enumitem} but I can't understand the reasons why the problem happened in the first place and got solved using enumitem. I nailed it to the following MWE :

\documentclass[varwidth]{standalone}
\usepackage[T1]{fontenc}
\usepackage[french]{babel}
\usepackage{verbatim}

\begin{document}
some text

\begin{itemize}
  \item an item
\end{itemize}

some more text

\begin{verbatim}
some verbatim
\end{verbatim}

\end{document}

which renders as

but I don't want any indentation on the some text line. Actually if I remove the french babel package, I get the desired output but as I'm writing in french, I would rather keep that :

Now if I remove the itemize part in the middle I also get the desired indentation on the first line but maybe that's because everything gets indented and the standalone is automatically cropped.

but I would rather keep that itemize, and when I remove the verbatim part, everything gets indented

I'm therefore not really capable to predict what happens here. I tried removing indentation using \noindent or \setlength{\parindent}{0pt} without success. I finally managed to get the desired output by adding the package enumitem, but I can't really determine what happened.
