Titlepage in article class when two-sided

Question

I am having troubles to set up a title page with article class.

My problem is same than here, but in addition to this example, I am using a two-sided document. If I add titlepage option here, the titlepage is not aligned in middle but aligned in twoside-style. However, for printing, I would prefer a middle-aligned titlepage. How is this possible?

How can I get \maketitle to create a separate title page with the article class?

\documentclass[titlepage,twoside]{article}

\begin{document}

\title{An example}
\author{Me}
\date{Today}
\maketitle

\section{First Section}
Hello world.

\end{document}

You can use geometry package and fix hmarginratio and later restore the original layout.

\documentclass[titlepage,twoside]{article}
\usepackage[pass,showframe]{geometry}       %% showframe just for demo

\begin{document}
\newgeometry{hmarginratio=1:1}    %% make layout symmetric
\title{An example}
\author{Me}
\date{Today}
\maketitle
\restoregeometry              %% restore the layout
\section{First Section}
Hello world.

\end{document}
