When serializing CSS declarations we now support combining multiple properties into a single shorthand property in some cases. This comes with a healthy dose of FIXMEs, including work to be done around supporting: - Nested shorthands (e.g. background, border, etc) - Shorthands which aren't represented by the ShorthandStyleValue type - Subproperties pending substitution This gains us a bunch of new test passes, both for WPT and in-tree
