如果在長標題中使用，Beamer footcite 引文會出現兩次

我注意到該\footcite命令在投影機內的字幕中使用時的奇怪行為。在工作範例中，假設第一幀有一個\footcite逐項項目，這將按預期工作。第二幀\footcite在表格內有一個標題，這再次按預期工作。第三幀與第二幀相同，只是它有一個跨越兩行的標題（長標題）。當標題被推到下一行時，就像第三幀的情況一樣，當預期只有一次時，兩次引用會出現在該幀的底部。這兩個引文是相同的，但腳印增加了（在這種情況下，#3 找不到，但#4 出現在標題中）。

有什麼辦法可以解決這種奇怪的行為嗎？我真的不想減少我的引文，以便將它們放在一行中。我不確定這是否是一些奇怪的錯誤或我使用\footcite不當。

標題內的腳註和腳註引用是有問題的；作為解決方法，您可以在標題\footnotemark內部\caption和外部使用：\footcitetext{<text>}

\documentclass{beamer}

\begin{filecontents*}{mybibfile.bib}
@ARTICLE{authora,
  author = {A. Aaaaa},
  title = {Some article},
  journal = {Journal of Dummy Article Names},
  year = {2012},
  volume = {99},
  pages = {1-5}
}

@ARTICLE{authorb,
  author = {B. Baaaa},
  title = {Another article},
  journal = {Journal of Dummy Article Names},
  year = {2012},
  volume = {99},
  pages = {6-10}
}

@ARTICLE{authorbb,
  author = {B. Baaaa},
  title = {Another dup article},
  journal = {Journal of Dummy Article Names},
  year = {2012},
  volume = {99},
  pages = {6-10}
}
\end{filecontents*}

附帶說明一下，beamer不需要對浮動使用放置說明符，因為beamer內部會停用浮動機制。

萬一十年後有人因為某些原因加載這裡caption包似乎只是修復它？

我對 TeX 不太了解，也許這會破壞其他東西...

...
\addbibresource{mybibfile.bib}

\usepackage{caption}

\usetheme{CambridgeUS}
...

enotez也為我奇怪的事情工作。
