It turns out, the Selectors 4 require ":scope" to match contextual reference element set, which would be the root node in querySelector: http://dev.w3.org/csswg/selectors4/#the-scope-pseudo Right now, we simply make ":scope" equivalent to ":root", which is not correct. Let's remove the partial implementation until we have time/energy to fully implement it.
