Complex footnotes

1 will be "2" (manually numbered), 2 will be "3" (anonymous auto-numbered), and 3 will be "1" (labeled auto-numbered).

• 1This footnote is labeled manually, so its number is fixed.
• 2This footnote will be labeled "3". It is the second auto-numbered footnote, but footnote label "2" is already used.
• 3This autonumber-labeled footnote will be labeled "1". It is the first auto-numbered footnote and no other footnote with label "1" exists. The order of the footnotes is used to determine numbering, not the order of the footnote references.
