[csswg-drafts] [css-conditional-5] Should `!important` be valid in a style query? (#12426)

cdoublev has just created a new issue for https://github.com/w3c/csswg-drafts:

== [css-conditional-5] Should `!important` be valid in a style query? ==
(This is a follow-up of recent changes from #12401 following the [resolution in #8376](https://github.com/w3c/csswg-drafts/issues/8376#issuecomment-2773374483).)

https://drafts.csswg.org/css-conditional-5/#style-container

  > The syntax of a `<style-feature>` is either the same as for a valid declaration

But the syntax of `<style-feature-plain>` has recently been made explicit with `<style-feature-name> : <style-feature-value>`, with `<style-feature-value>` defined as `<declaration-value>`, which does not accept `!`.

In Chrome, it seems that `style(--custom: 1 !important)` evaluates to `true` regardless of whether the declaration of `--custom: 1` for the container has a priority or not.
