如何将较长的框架标题放入一行？

Question

我使用命令\resizebox将长框架标题调整为一行，但是它不起作用，如下图所示。

这是一个 MWE。

\documentclass[compress]{beamer}
\usetheme{Warsaw} 

\title{title}
\author{author}

%%%%%
\begin{document}

\begin{frame}{\resizebox{\textwidth}{!}{very very very very long frame title}}
very very very very long frame title
\end{frame}

\end{document}
