False positive "invalid_ref" for IDs on links

[MasonRemaley]

I'm trying to implement footnotes. Here's my footnote, this would go inline in a paragraph:

[1]($link.ref("1").attrs("footnote")

Later in the text, I'd have the content for the footnote, as another link:

[^1]($link.url("https://example.com").id("1"))

However, I get an error saying that "1" is an invalid ref. If I change the second snippet to be a heading instead of a link, then it works as expected.

[EDIT] Maybe ref thinks that only sections can be linked to? I can see why that would be reasonable in most cases, but in the case of footnotes this is a bit annoying because I don't want all my footnotes to show up in the table of contents.

Linking to ids defined in the same content page is a corner case (totally legitimate one, but still) that is not implemented yet. We had some false negatives before when linking to non-section Ids from superhtml, but this one is a separate thing.

Now that v0.7.2 is out, this is currently at the top of my list of missing features to implement.

Nvm I've actually now looked into it and I already had implemented this, I just forgot about it lol.

I tried to reproduce the bug but failed: the ref gets recognized successfully and everything is linked successfully.

Make sure you're using the latest release of Zine and then please commit a full repro in a branch for me to take a look at. What's almost certainly happening is that the footnote is placed in a location of the markdown AST where I forgot to properly record seen IDs.
