Citation hover popup uses unsorted data-cites order instead of rendered CSL order

Description

When rendering citations with author-date CSL styles in Quarto (HTML output), the in-text citation cluster is correctly sorted according to the CSL <sort> rules (e.g., alphabetical by author). However, the hover popup (the tooltip showing full reference entries) displays items in the original citation order from Markdown, not the sorted display order.

This produces inconsistent and confusing results: the text and the tooltip list the same references in different orders.

Example

Source Markdown

[@lipman1997; @dikotter2015; @gladney2004]

Expected output (APA / author-date):

Text (correct):

(Dikötter, 2015; Gladney, 2004; Lipman, 1997)

Hover popup (expected to match text):

Dikötter F (2015)…
Gladney DC (2004)…
Lipman JN (1997)…

Actual hover popup (unsorted):

Lipman JN (1997)…
Dikötter F (2015)…
Gladney DC (2004)…

Diagnosis

Quarto builds citation tooltips from the data-cites attribute in the HTML:

<span class="citation" data-cites="lipman1997 dikotter2015 gladney2004">
  …
</span>

Pandoc correctly sorts the inline text, but Quarto’s tooltip logic reads data-cites as originally typed, not in the rendered order.
Thus, the popup order diverges from the visible citation order whenever the CSL style defines a <sort>.

Expected Behavior

The hover popup should respect the sorted CSL order—i.e., the same order that appears in the rendered citation text.

Steps to Reproduce

1. Use any author–date CSL style that defines a <citation><sort> (e.g. apa.csl).
2. Create a .qmd file with the example citation above.
3. Render to HTML (quarto render example.qmd).
4. Hover over the citation cluster: the popup order differs from the visible order.
