[BUG] - ES modules import "./some-lib.css" seems not to end up in the shadow-root

Are you referring to a third-party component library (such as vuetify)?

Are you referring to a third-party component library (such as vuetify)?

For example. Anything that is imported with a import "style.css" in the head. This style will not end up in the shadow dom even if the import was done in a sub component. The example I provided seems to be the original one, sorry for that I had it working but might have lost the link somehow...

The important thing is NOT @import of CSS that works, but import of ES modules with css. E.g. with libs that use this one here: https://www.npmjs.com/package/vite-plugin-lib-inject-css
