------- Additional Comments from Andreas Kling <kling at webkit.org>
Uploading my current WIP, which passes all layout tests, but lacks ChangeLog
and a solution for supporting the old behavior of Attr::style() which is
exposed as Obj-C API.
Immediate follow-up work after this patch would be removing the "preserveDecls"
argument from attributeChanged() and killing CSSMappedAttributeDeclaration,
moving the remaining logic into StyledElement's helpers.
