+% The following patch of \cs{footnote} assumes that the optional arguments of
+% \cs{footnote} and \cs{footnotemark} match. Since this is not the case in
+% \class{beamer} based documents, and since \class{beamer} extents the
+% syntax of \cs{footnote} in a way we don't support, we don't apply the patch there.
