Alphanumeric produce different cite keys in text and bibliography

[tkw1536]

Description

I am using the alphanumeric citation style. When citing two entries from a bib file that would produce the same key (e.g. same author and same year), they render with an a and b suffix where they are cited. However, in the bibliography, they appear without the same suffix.
Without manual tweaking, with #show rules and the like I was expecting the same label to be used in both places.

As a minimal example, consider the following bib file:

@article{first,
  title={First Thing},
  year={2024},
  author={Jane Doe}
}

@article{second,
  title={Second Thing},
  year={2024},
  author={Jane Doe}
}

The alphanumeric cite styles assigns both articles the key Doe24.

Using the following main file:

#set cite(style: "alphanumeric")

I cite the first thing #cite(<first>) and the second thing #cite(<second>). 

#bibliography("example.bib")

The pdf renders as:

Notice how the keys listed in the main body are [Doe24a] and [Doe24b] whereas in the bibliography section they are both shown as [Doe24]. There also appears to be an extra an and b at the end of the entries.

I did find two related issues, but neither of them seem to cover exactly this.

• Inconsistent styling with bibliography.full: true typst#3986, but I'm not using bibliography.full
• Force CitationLabel in bibliography when using alphanumeric citation labels typst#2707, but that's closed and this is still a problem
