### Description

This question is related to #290 . `backref=true` seems not working for generating backlinks in the output pdf. A minimal reproducible example is below:

`index.qmd` file:
```qmd
---
title: "Start Blogging with Quarto"
date: "2023-06-10"
bibliography: [local.bib]
format:
  html: default
  pdf:
    cite-method: biblatex
    biblatexoptions:
      - "backend=biber"
      - "backref=true"
    keep-tex: true
---

For testing backref. [@navarro2022]
```

With a `local.bib` file:
```
@online{navarro2022,
  author = {Navarro, Danielle},
  title = {Porting a Distill Blog to Quarto},
  date = {2022-04-20},
  url = {https://blog.djnavarro.net/posts/2022-04-20_porting-to-quarto},
  langid = {en}
}
```
The command I used is `quarto preview index.qmd --to pdf`.

Apart from the above question for generating backlinks in pdf, **can we do the same thing for HTML**? i.e., adding back links in the reference list to go back to some specific locations of the HTML where the article got cited. It would be something like the footnote backlink I guess, which is a nice feature.

Thanks!
