[csswg-drafts] Flattened element tree and pseudo-elements

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

== Flattened element tree and pseudo-elements ==
In https://github.com/whatwg/html/issues/3805 a concern was raised by @bzbarsky (perhaps on behalf of @MatsPalmgren) that expressing `details` through shadow trees results in a placement of `::before` and `::after` that's not desirable.

So the question is whether `::before` and `::after` on a host element should perhaps be shadow tree aware and end up "assigned" to a slot. This would perhaps be somewhat more natural given that element children end up being assigned.
