### Bug description

I am writing a book and I found that the HTML version's citation hover is broken when I use `nature.csl`. Maybe it's for all superscript citation styles?

To reproduce:
- create book
  ```shell
  quarto create-project hover-bug --type book 
  ```
- add `csl: science.csl` to `_quarto.yml`
  - `quarto preview`
  - go to intro page, note that mouse hover over ref brings up tooltip 😃 
- add `csl: nature.csl` to `_quarto.yml`
  - `quarto preview`
  - go to intro page, note that mouse hover over ref **does not** bring up tooltip 😢 

Here are the CSL files I used:
[styles.tar.gz](https://github.com/quarto-dev/quarto-cli/files/9509088/styles.tar.gz)

I'm running Quarto on WSL Ubuntu 18.04, on Windows 10
