Is there anything left blocking CSS Cascade 3 or can this bug be closed?

Per MDN it looks like we already implement 'initial' and 'all' - can't seem to find the bugs for those offhand though - would be good to add them as dependencies (even if already closed).

* We need someone familiar with the codebase to look into whether we have implemented "The scoping mechanism" as noted in MDN https://developer.mozilla.org/en-US/docs/Web/CSS/CSS3 and add that bug as dependency.

* Documented test results showing we pass all https://test.csswg.org/harness/review/css-cascade-3_dev/ tests (which we don't currently, e.g. https://test.csswg.org/suites/css-cascade-3_dev/nightly-unstable/html/cascade-import-002.htm appears to fail four examples in 59.0a1 Nightly for example)

The initial keyword was unprefixed in bug 806068 and the 'all' property was added in bug 842329.

Updated: cascade-import-002 fails are the fault of test file, not us. Bug 1428932 is now tracking the external bug to get that test fixed.
