Workaround for anyone finding this issue:

diff --git a/extension/footnote.go b/extension/footnote.go
index d1b67aa..b856d92 100644
--- a/extension/footnote.go
+++ b/extension/footnote.go
@@ -91,8 +91,8 @@ func (b *footnoteBlockParser) Close(node gast.Node, reader text.Reader, pc parse
 	} else {
 		list = ast.NewFootnoteList()
 		pc.Set(footnoteListKey, list)
-		node.Parent().InsertBefore(node.Parent(), node, list)
 	}
+	node.Parent().InsertBefore(node.Parent(), node, list)
 	node.Parent().RemoveChild(node.Parent(), node)
 	list.AppendChild(list, node)
 }

This solution seems kind of janky to me though, so I didn't want to submit it as a PR without prior discussion.

Also, the ideal order IMO would be before parent child after (which is what GitHub seems to do), but achieving that probably requires some additional logic.
