[texhax] beamer vs \tag*{\ref*}

[Victor Ivrii]

The example below does not work in {beamer} but works in {article} (if
removed \begin{frame} and \end{frame} and load hyperref and ams math.

Also it works in beamer if

\tag*{$(\ref*{eq-1})^*$}\label{eq-1-*}

is replaced by
\tag*{$(1)^*$}\label{eq-1-*}

\documentclass{beamer}
\usepackage[english]{babel}

\begin{document}
\begin{frame}
\begin{equation}
1+1=2
\label{eq-1}
\end{equation}

\begin{equation}
1+2=3
\tag*{$(\ref*{eq-1})^*$}\label{eq-1-*}
%\tag*{$(1)^*$}\label{eq-1-*}
\end{equation}

\end{frame}
\end{document}
