Footnotes link to the first occurrence on the page, which is wrong if both Q and A have footnotes

https://meta.codidact.com/questions/278294:

If there is a proper footnote (using the links) in the question of the post and in any of the answers, and you click on a footnote in the answer, it will lead to the footnote that is part of the question.

Meta post has examples that demonstrate the problem.

In case it affects priority, this has been raised again on Meta.

For completeness, note that this also affects questions that have no footnotes, if more than one of the answers have footnotes.

I see this is marked "deferred". Is that because it requires changing a markdown library? (Did I understand that correctly from discussions elsewhere?)
