### Bug description
When previewing a website in Firefox using `quarto preview`, only the homepage loads; whenever clicking any other link in both the navbar or sidebar, the homepage reloads. Quarto gives the following output on clicking a link (but only sometimes):
```
GET: /about.html
WARNING: connection closed before message completed
GET: /
```

I'm using Quarto v1.2.242 and see the result both running on Windows 11 in Powershell and in WSLv1.

### Reproducing
1. Create a new website using `quarto create project website`.
2. Execute `quarto preview`.
