Description

If the loaded chunk didn't have any deps, vite:preloadError was not emitted.

For example, the event is not emitted for https://stackblitz.com/edit/vitejs-vite-ho9n9z?file=main.js,counter.js and is emitted for https://stackblitz.com/edit/vitejs-vite-eubg1i?file=main.js,counter.js
The difference between them is that counter.js imports counter.css in the latter one.

I think we should add a section about vite:preloadError somewhere in the docs, but I'm not sure where to put this. 🤔

I think we can add the section in the docs in another PR. Maybe another section after Chunking Strategy? (we could also think of removing the vendor plugin bits from Chunking Strategy, it may not be needed there anymore)
