Footnotes don't allow footnote references in the text

[KajKandler]

This is a foo [^foo].

This is a bar [^bar].

[^foo]: A foo is beautiful. This is in contrast to a bar [^bar].

[^bar]: A bar is very common.

Is rendered as

1. A foo is beautiful. This is in contrast to a bar [^bar].
2. A bar is very common.

It looks to me as if URLs in a footnote are not rendered either:

This is body text, and a footnote.[^f]

[^f]: The footnote includes [a link][1].

[1]: https://example.com

Renders as:

This is body text, and a footnote.¹

1. The footnote includes [a link][1]. ↩

Inline URLs work fine (e.g., [a link](https://example.com) renders correctly in the footnote).
