[csswg-drafts] [css-cascade] Allow more support features in `supports()` for `@import` (#13759)

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

== [css-cascade] Allow more support features in `supports()` for `@import` ==
[css-cascade] Allow more support features in `supports()` for `@import`

[CSS Cascade 4-6](https://drafts.csswg.org/css-cascade-6/#typedef-supports-import-condition) define `supports()` for `@import` as accepting `<supports-condition> | <declaration>` with `<supports-condition>` pointing to [CSS Conditional 3](https://drafts.csswg.org/css-conditional-3/#typedef-supports-condition), which only defines `<supports-decl>`.

Is it an oversight or intentional? Major browsers have [supported](https://wpt.fyi/results/css/css-cascade/parsing/supports-import-parsing.html?label=master&label=stable&aligned) `selector()`, `font-format()`, `font-tech()`, for some time.
