Nah, you're fine.  From a layout perspective, pseudo-elements are
"real" elements, just like everything coming from the document.
However, attr() refers to qualities that pseudo-elements don't have,
and so it's more useful to have it instead refer to the superior
parent when used inside of a pseudo-element.
