Summary position:-webkit-sticky is not preserved across a copy

Right now we don't copy position:-webkit-sticky. This is because: 1. When copying styled elements, we parse the style properties again 2. CSSParserContext has a flag which can disable parsing -webkit-sticky 3. There are two constructors to CSSParserContext: one that takes a document and sets up the aforementioned flag, and a simple one that doesn't take a document and sets all the enableFoo flags to false 4. At the relevant place within copy code, we are far removed from the Document object, so we instead call the second constructor, thereby disabling parsing of -webkit-sticky

It would be a good idea to simply get rid of this runtime flag altogether.

The flag is gone. This is solved.
