I was going to send a test for `:focus` via wpt, but then realized it was probably not spec-compliant with the new rules people want to follow for :focus, so I filed https://github.com/w3c/csswg-drafts/issues/4555 instead. Testing `:hover` / `:active` via wpt looked quite a bit of a hassle. Differential Revision: https://phabricator.services.mozilla.com/D55591 --HG-- extra : moz-landing-system : lando
