Revision e8c4654cef692388e68e8ded7a9316d6bd613570 authored by Darren Shen on 06 April 2018, 07:51:02 UTC, committed by Chromium WPT Sync on 06 April 2018, 07:51:02 UTC 
[css-typed-om] Add support for background properties.
 
We cannot support background-repeat and background-position yet because
they are both implemented as shorthands in Blink, but are not shorthands
in the spec.

We'd need to refactor the existing code to allow shorthands to reify
as proper Typed OM objects. There are also some tricky bits to support
styleMap.set with shorthands given a proper Typed OM object.
