handle case where link text contains a footnote

[yshavit]

link text can't contain a link (by definition), but it could contain a footnote.

I should check for that. I bet it's wrong right now.

• check for md output
• check for json output
• check for footnotes that contain other footnotes

[yshavit]

- AAA: [footnote [^1] in a link](https://example.com)
- BBB: footnote countains foonote[^2]
- CCC: footnote contains link[^3]

[^1]: the link's footnote text
[^2]: this footnote contains[^a] a footnote
[^3]: this footnote contains a [link][3a]
[^a]: this is the footnote's footnote

[3a]: https://example.com/3a

---

• AAA: footnote 1 in a link
• BBB: footnote countains foonote²
• CCC: footnote contains link³

Footnotes

1. the link's footnote text ↩

2. this footnote contains⁴ a footnote ↩

3. this footnote contains a link ↩

4. this is the footnote's footnote ↩

Oh actually, footnotes-within-links don't work. I just hadn't noticed that it's rendered wrong, but it is.

mdast handles these the same as GH does: see https://gist.github.com/yshavit/6af0a784e338dc32e66717aa6f495ffe

Can you also have footnotes that reference themselves? ¹
