There are some historical #idfefs for iOS that were done the iOS was the only platform to have overlay scrollbars, before these came to macOS, but these cause some surprising behavior in layout tests, particularly because RenderLayerScrollableArea::showsOverflowControls() can return a different result depending on whether we use composited scrolling.

This isn't so simple. Lots of nasty interactions between mock scrollbars, custom scrollbars etc.
