Thank you for looking into this, Emilio!

I have just tested the ':host > div' solution that you suggested, and it does indeed accomplish the selection of direct descendants across all browsers (excluding IE, which is expected), so we have a path forward..

If :scope is indeed not supposed to be working for shadow roots, I'd suggest improving the CSS Selectors Level 4 spec, so that this is mentioned explicitly in :scope and there's no ambiguity:

"If the :scope elements are not explicitly specified, but the selector is scoped and the scoping root is an element, then :scope represents the scoping root;"

change to =>

"If the :scope elements are not explicitly specified, but the selector is scoped and the scoping root is a true (not virtual) element, then :scope represents the scoping root;"

would you agree?
