How to add tracking (letterspacing) to author names in bibliography?

Hi all,

I am using a bibliography style that requires author names to be typed in small caps. See the following example generated in LaTeX:

I got a CSL file for this specific citation format, and I see it uses the font-variant=“small-caps” parameter for author values, which seems to be correctly read and rendered by Typst. However, I want to add tracking (letterspacing) to the small caps in order to improve readability. I have been adding tracking with success in other parts of my document for text in all caps and small caps.

For small caps in specific, I used this:

#show smallcaps: set text(tracking: letterspacing)

It works when I manually use smallcaps throughout the document, but does not affect the text in the bibliography. Since Typst is actually rendering the small caps for author names in the bibliography, I wonder why it is ignoring the show-rule.

An example of what I am getting in Typst (I still have to do some fixes to the CSL file, so ignore the poor formatting):

You can see that the small caps are correct, but it is ignoring the tracking. However, it works if I apply it globally with a set-rule, but in this case, it affects other parts of the bibliography entries.

Does anyone know a workaround or a way to troubleshoot the bibliography generation by Typst?

Thank you in advance!
