However, this means that we know there are not two interoperable
implementations of this part of CSS 4 Selectors, so it shouldn't be
able to progress to PR.  Since browsers all behave the same, it makes
the most sense to just spec what browsers do, and add a test.  I don't
see any justification for keeping the spec as-is except if you think
that the spec should be theoretically pure rather than matching
implementations.
