@import rule with supports() and/or layer() parsed as Raw

[bartveneman]

CSSTree doesn't seem to Lex/parse layer() and supports() in @import rules.

Reproduction

Repro on StackBlitz

For each of these examples the node's prelude is type Raw:

@import "my.css" layer;
@import "my.css" layer(test);
@import "my.css" layer supports(display: grid);
@import "my.css" layer (min-width: 768px);
@import "my.css" layer(base) supports(accent-color: green) (min-width: 768px);

Validator results

I'm slightly confused because the validator does recognise even the last example with their correct token types. Link

I'd be happy to contribute a fix for this, but I got stuck on trying to add new logic to import.js, so I might need a bit of guidance.

It looks like @ngtr6788 already implemented a fork for this for Svelte over here: https://github.com/sveltejs/svelte/pull/9098/files#diff-ed2fad2b231aca18fc2b692be85898d0099355fc12ceca4bdd2990faf5159d94, although it doesn't seem merged yet.

This was implemented and will be available in next major version soon.

The validator works on tokens, not AST.

Thanks for the clarification!

A new version will be published this week.
