[🐞] weirdness with CSS import names in dev

[wmertens]

Which component is affected?

Qwik City (routing)

Describe the bug

In https://stackblitz.com/edit/qwik-style9?file=src%2Froutes%2Findex.tsx, you can see that in dev mode, the word count is white. Then when you click + or -, it will become blue or red depending on odd or even.

This happens because the initial load has the style9-generated CSS with a path that doesn't exist, and then the update re-renders the count with a function that imports the CSS with the correct name.

What is going on, and how to fix it?

Reproduction

https://stackblitz.com/edit/qwik-style9?file=src%2Froutes%2Findex.tsx

Steps to reproduce

wait for dev mode to start, and click + or -

Look at the initial network load, it tries to load the CSS with the wrong name and fails. After that, it will load the CSS with the correct name, /@id/...

unsure what's happening, but it seems to be a style9 vite plugin thing now in 1.8+. StyleX also doesn't actually work but that doesn't even try to load the CSS.

The original problem was that qwik processed files before style9/x could look at them, and that's fixed, so closing.
