# Footnotes duplicated with overlays and show notes on second screen

When attempting to add a footnote to a frame title, the footnote is duplicated if show notes on second screen is set.

\documentclass{beamer}
\setbeameroption{show notes on second screen}

\begin{document}

\begin{frame}{Footnotes\footnote{Footnote 1}}
Hello
\pause
World
\end{frame}
\note{Note}

\end{document}


This only happens if the footnotes are in the frame title, and does not happen if there are no notes or with show notes. This happens for all of the overlays that I tried.
