Backlinks for references in html output are missing

I have:

• searched the issue tracker for similar issues
• installed the latest version of Quarto CLI
• formatted my issue following the Bug Reports guide

Bug description

No response

Steps to reproduce

Quarto.qmd:

---
bibliography: ref.bib
format:  html
---
# Title
Reference one, [@example01]
Reference two that is the same as one, [@Nobody007]
Reference three new reference, [@example01]

# References
::: {#refs}
:::

Refs.bib:

@misc{ example01,
       author = "Good Person",
       title = "His Article",
       year = "1988" }

@misc{ Nobody007,
       author = "Nobody Jr",
       title = "My Article",
       year = "2006" }

Actual behavior

Correctly produces html with two citations instead of three since one is repeated. But it won't produce backlinks to where it came from.

Expected behavior

Should be:

https://github.com/user-attachments/assets/55acdd6b-9723-4468-bfb0-01232bac9c6d

instead shows no backlinks.
Looks like this was discussed for pdfs before orgs/quarto-dev/discussions/5895 and also corrected(?) too but not so for html. Based on the solution provided by @anrath seems like it's a simple fix but it's a simple feature to have it baked in and also I don't want html with js rendering on it.

Reproduce the issue with Quarto.qmd and ref.bib using the HTML format, then inspect the generated citation and references output. Read the linked discussion 5895 for the prior PDF approach and compare the result with the expected backlinks; done means repeated citations link back to every citation location without requiring JavaScript.
