当 `\begin{enumerate}` 后面跟着 `\ref{x}` 时，hyperref 会使 `\ref{x}` 指向 `\label{x}` 的最后一页（使用 enumerate 包）

Question

以下文档显示了该问题：

\documentclass{scrreprt}
\usepackage{amsmath}
\usepackage{amsthm}
\usepackage{enumerate}
\usepackage{hyperref}

\newtheorem{thm}{Theorem}[chapter]
\begin{document}
  \chapter{first chapter}
  The reference to theorem \ref{thm:structureunoriented1} is correctly displayed (2.1 in this case) but points to the last page of the document with {\ttfamily warning  (pdf backend): unreferenced destination with name 'thm.2.1'} during compilation.
  \newpage
  \chapter{second chapter}
  \begin{thm}\label{thm:structureunoriented1}
%%    \phantom{x}  % Uncommenting this line prevents the problem
    \begin{enumerate}[(i)]
        \item This is the part 1 of the theorem I want to refer to.
        \item This is the part 2 of the theorem I want to refer to.
    \end{enumerate}
  \end{thm}
  \newpage
  \chapter{third chapter}
  This is where I land when klicking on the reference.
\end{document}

我不确定谁是罪魁祸首，但其中一个包hyperref是enumerate，对吧？有办法避免这个问题吗？毕竟\phantom不是很优雅。在工作后放置标签\end{enumerate}，但随后我落在了定理的底部。
