[🐞] CSS is being included multiple times on the page

[cmbartschat]

Which component is affected?

Qwik Runtime

Describe the bug

The same CSS file is being inlined multiple times.

I have two separate components including the same style.css with useStyles$. If I render the same component multiple times, the css file is only included once, but with multiple components, there are duplicate <style> elements inserted.

Reproduction

Steps to reproduce

• Open the link
• npm run preview
• Inspect the section elements
• See that there are two css rules that target it

Hi @cmbartschat
I can't reproduce the issue, with the latest version of Qwik, is it still valid?

The CSS is included twice because you include it twice in two different components.

Although probably the css import should result in the same css qrl somehow.

Here's a repro with the latest qwik.new

https://stackblitz.com/edit/qwik-starter-ihm7vt?file=src%2Froutes%2Fsection-b.tsx,src%2Froutes%2Fsection-a.tsx,src%2Froutes%2Fservice-worker.ts

We still see the duplicated styles:

The problem goes away if I switch to a shared hook like:

import { useStyles$ } from '@builder.io/qwik';

import styles from './shared-styles.css?inline';

export const useSharedStyles = () => {
  useStyles$(styles);
}
