### Bug description

Using template website created with `quarto create`, and editing YAML in `about.qmd` to specify a couple of formats:
````
---
title: "About"
format:
  revealjs: default
  pdf: default
---
````
I would expect if I hit RStudio's "Render Website" I would have `about.pdf` and `about.html` (Revealjs slides) in `_site/`, but I'm missing `about.pdf`:
```
_site
├── about.html
├── index.html
├── search.json
├── site_libs
└── styles.css
```

I actually get the same thing from `quarto preview` (no `about.pdf`), although if I then navigate to `about.html`, `about.pdf` is generated. (Browsing to `about.html` from the Preview of "Render Website", does not trigger a render of `about.pdf`). 

`quarto render` generates all files as expected.

I thought the problem didn't occur with `pdf` and `html`:
```
---
title: "About"
format:
  html: default
  pdf: default
---
```
~~But, I seem to be having the same problem with "Render Website" for this too.~~ While `about.pdf` isn't generated initially, it does get triggered if I hit the PDF version in the "Other Formats" links.

This feels a bit like #4469 - but I'm not convinced they are exactly the same problem.
