Referencing a footnote multiple times lists the footnote once for each reference #241
Description
Originally posted here: gohugoio/hugo#1912
I don't know if this is intended or not (what would the return link do?), but I feel like duplicating the footnote is not the right way to go. The link even points to the uppermost footnote (instead of the one generated for this link).
An effect of this is if you try to reference the footnote itself in the footnote, Hugo crashes.
