Automatic update from web-platform-tests vt: iframe scrollbars paint last during transition In a main frame, scrollbars paint during the kOverlayOverflowControls phase while in an iframe they paint during kSelfBlockBackgroundOnly. The former causes the scrollbars to avoid being part of the root snapshot due to the way we handled https://crbug.com/1303081. The latter causes the scrollbar to be painted into the iframe's root snapshot which is unintended. This CL changes the paint order of iframe scrollbars to match the main frame since iframes also cannot have content that paints over top of a scrollbar.
