Re: Bug: When exporting to PDF an Org file where multiple footnotes share the same definition, only the first footnote is clickable [8.3.4 (8.3.4-39-ge0acd8-elpaplus @ /home/jorge/.emacs.d/elpa/org-plus-contrib-20160418/)]

Indeed. I don't know any other way to handle repeated footnote markers
in LaTeX.

You can retrieve element referenced as "org925ce52" with

  (cdr (assoc "org925ce52" (plist-get info :internal-references)))

It's a bit low-level, but it is useful, it could be factored out as
a function in "ox.el".
