It is not obvious why ignoring the element size is a useful default behavior. But I suppose that discussion is out of scope here and would better be discussed in a CSS-relevant forum.

Yeah, feel free to raise it in www-style if you're interested.
Otherwise, fantasai and/or I will take care of it in due time, when we
have time for it.

It says "If the computed value of the part of the 'content' property that ends up being used is a single URI, then the element or pseudo-element is a replaced element. The box model defines different rules for the layout of replaced elements than normal elements. Replaced elements do not have '::before' and '::after' pseudo-elements; the 'content' property in the case of replaced content replaces the entire contents of the element's box." But I can't tell if that matches what you say or is the opposite.

Right, Content is out-of-date and hasn't been sanity checked.  Don't
let the recent-ish date fool you; it's just a stripped-down version of
the older 2003 draft, and the remaining parts haven't been seriously
gone over yet.
