The update doesn't actually do anything until the resolver is created, just skip the tree walk. This also removes the special case for document from StyleSheetCollection which didn't make any sense. It would cause us to discard the entire resolver whenever the sheets in the document changed which is far more work than is actually needed. We probably are missing some font invalidation code now, but we can add that back later. R=ojan@chromium.org Review URL: https://codereview.chromium.org/836383005
