Inconsistent styling with bibliography.full: true

[tingerrr]

Description

When using bilbiography(full: true, ...) to show all references, the styling seems to be inconsistent when a cite style like alphanumeric is used. The markers fall back to the biliography style (ieee in my case).

full: true without explicit cite	full: true with explicit cite

I assume this is because alphanumeric is a style on cite only, so the lack of cite elements means the styling isn't applied.

At face value, I can see that this "works as intended", but I never understood (or asked) why alphanumeric is only a style on cite in the first place. I suppose that's related to CSL.

I did not attempt minimizing this, but this should suffice:

#set cite(style: "alphanumeric")
#bilbiography(full: true, "bib.yaml")

// cite some key always to enforce the style
#cite("some-key")

// comment this out to observe the difference
#for key in yaml("bib.yaml") {
  cite(label(key))
}

Tested using typst 0.11.0 (1e645b39).

Able to replicate this in the webapp (url: https://typst.app/project/rNnLsTjkhkCnV5I0HqrvQb)
But had to unpack the iteration to key-value since the provided example-code doesn't compile:

#set cite(style: "alphanumeric")
#bibliography(full: true, "bib.yaml")

// cite some key always to enforce the style
#cite(<harry>)

// comment this out to observe the difference
#for (key,value) in yaml("bib.yaml") {
  cite(label(key))
}

bib.yaml (example taken from https://github.com/typst/hayagriva/blob/main/docs/file-format.md)

Looks like un-intended/buggy behaviour to me.

My bad, I wrote it from memory and forgot about that.

Okay you can actually reduce this by alot more to demonstrate the issue/behavior.

#set cite(style: "alphanumeric")
#bibliography(full: true, "bib.yaml")
#cite(<harry>)

This renders the actually cited entry <harry> with the specified "alphanumeric" style but the rest of the entries with the auto style (which defaults to "ieee"):

This changes though once you specify the bibliographies style:

#set cite(style: "alphanumeric")
#bibliography(full: true, "bib.yaml", style: "apa")
#cite(<harry>)

Where the rendered bibliography gets styled according to the specified "apa" style , but the symbol generated by #cite is still in the "alphanumeric" style.

After some reconsideration im not sure if this would actually be a bug/unwanted behaviour 🤔.
But should definitely be documented in my eyes

It seems to come down to the fact that we cannot specify the reference back link style on the bibliography, if the CLS style is unsuitable for it. It is inferred from the cite element that's used, if there is no cite element it isn't inferred correctly.

But I think the reference back link style could fall back to the cite style chain where applicable.

Using more than style also causes interesting results depending on whether a cite group can be created or not:

#set cite(style: "alphanumeric")
#bibliography("assets/bib.yaml", full: true)

@electronic
// <-- remove this blank line to create a cite group
#cite(<harry>, style: "chicago-author-date")

With cite group:
