Footnotes from HTML are not rendered natively as footnotes

[mbanerjeepalmer]

Using the following idiom (taken from https://html.spec.whatwg.org/multipage/semantics-other.html#footnotes)

    <p> Announcer: Number 16: The <i>hand</i>.
    <p> Interviewer: Good evening. I have with me in the studio tonight
        Mr Norman St John Polevaulter, who for the past few years has been
        contradicting people. Mr Polevaulter, why <em>do</em> you
        contradict people?
    <p> Norman: I don't. <sup><a href="#fn1" id="r1">[1]</a></sup>
    <p> Interviewer: You told me you did!</p>

    <section>
        <p id="fn1"><a href="#r1">[1]</a> This is, naturally, a lie,
            but paradoxically if it were true he could not say so without
            contradicting the interviewer and thus making it false.</p>
    </section>

Using commonmark as the output:

Announcer: Number 16: The *hand*.

Interviewer: Good evening. I have with me in the studio tonight Mr Norman St John Polevaulter, who for the past few years has been contradicting people. Mr Polevaulter, why *do* you contradict people?

Norman: I don't. <sup><a href="#fn1" id="r1">[1]</a></sup>

Interviewer: You told me you did!

<div class="section">

[\[1\]](#r1) This is, naturally, a lie, but paradoxically if it were true he could not say so without contradicting the interviewer and thus making it false.

</div>

Instead what is expected is native footnotes: https://pandoc.org/chunkedhtml-demo/8.19-footnotes.html

I can't see any other questions about this. I must be doing something wrong at a basic level.

There is #3724 , but that focuses on reversibility, not getting it right in one shot.

Thanks!

See #5294. In your case you don't have the aria-roles, so #5294 wouldn't help -- but I think that using the aria-roles is the only really reliable way to distinguish footnotes from other sorts of links.

Thanks for clarifying. Is it worth mentioning in the docs that this isn't supported at the moment?

As for implementation, agree that aria would be a good start. My uneducated opinion is that the WHATWG idiom can safely said to be a footnote. What else would a superscript within an anchor (or vice versa) which references another anchor tag that references the original, be? I have no idea what the implementation implications are, though. I may throw together a custom lua script using these principles and see how that works.
