[css-cascade-6] Absolutize Relative Selector Syntax within @scope?

[dshin-moz]

CSS Nesting spec explicitly absolutizes any use of relative selector syntax by inserting &. Seems consistent, then, to absolutize relative selector uses in @scope by inserting :scope.

By extension (Since we're treating it like scoped style rules), <scope-end> should do the same, if the relative selector syntax is used. (Aside - <scope-end> is solely defined as <forgiving-selector-list>)

Ah, I think this is already resolved in #9621, right?

Ah - missed, that. Thanks!
