@romandev, can you rebase this so that we get a new Travis run? https://pulls.web-platform-tests.org/pull/8772 doesn't have any results (@mattl FYI, maybe because of downtime?)

This should be merged together with w3c/csswg-drafts#2123, right?

(This is an open PR that would require changes if I do #9026, that's why I'm here.)
