We convert style flushes on a document into layout flushes on the parent, just in case the document has media queries that depend on the viewport size. But most documents don't, right? Is it worth flagging the prescontext (during media query matching) if the media query depends on the viewport size, and then conditioning the promotion to Flush_Layout on that flag?
