The analysis is good, but unfortunately the patch has a flaw.

In fact, your patch work in that particular situation, but not if
a footnote definition ends with a list, nor if it ends with a link. To
solve the latter, you need to insert a white-space before the closing
bracket. To solve the former, I thought adding a newline instead of the
white-space was enough, but it now appears it was a bad idea.

Thus, the solution lies elsewhere.
