citations-hover not work when reference-location set to margin

Bug description

Hi I'm using Quarto 1.4.550. As the example below shows, it seems that citations-hover doesn't work when reference-location set to margin. Strange that this issue is triggered only if there is actually a footnote in the body.

Steps to reproduce

---
title: "Test"
bibliography: test.bib
format:
  html:
    reference-location: margin
    citations-hover: true
---

Footnote test^[Footnote.].

Citation test [@knuth_art_1997].

with a valid .bib file triggers this issue.

Expected behavior

The hover popup shows when mouse hovering over a citation.

Actual behavior

The hover popup does not show.

Tested crossref-hover and citation-location as well. crossrefs-hover is also vulnerable to this issue, however setting citation-location to margin won't interfere with citations-hover nor crossref-hover.

These behaviors are not consistent, and I can't find any documentation clarifying them so far...
