Status: RESOLVED FIXED

(Core :: Layout, enhancement, P3)

Description

https://drafts.csswg.org/css-content/#valdef-content-none

On elements, this inhibits the children of the element from being rendered as children of this element, as if the element was empty.
...
In neither case does it prevent any pseudo-elements which have this element or pseudo-element as an originating element from being generated.

There's a r+ patch which didn't land and no activity in this bug for 2 weeks.
:mats, could you have a look please?
