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
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.
