Description Takashi Sakamoto 2012-11-19 03:40:01 PST 
Currently updating any styles in shadow dom trees causes full style update. However, the update doesn't affect document tree. So we should update only the affected shadow dom trees.

Comment 2 Takashi Sakamoto 2012-11-19 04:07:26 PST 
This WIP patch contains:
(1) add ShadowStyleSheetCollection and move all styles in shadow dom trees from DocumentStyleSheetCollection to ShadowStyleSheetCollection.
(2) update HTMLStyleElement and StyleElement to provide treescope information for ShadowStyleSheetCollection.
(3) add StyleShadowResolver and make StyleResolver to invoke the resolver.
(4) use ShadowStyleSheetCollection to update RuleSets in shadow dom trees instead of all RuleSets.

This WIP patch also makes document.stylesheet not to include styles in shadow dom trees.
