We currently don't create individual layers for subframe scrollbars, since subframes usually have a thebes layer behind them that spans the whole scroll port, and the scrollbars can merge into that background layer. However, this is not the case for overlay scrollbars: Overlay scrollbars cause a new thebes layer to be created in front of the scrolled layer, and if both horizontal and vertical scrollbars are visible, that front layer is much larger than necessary.
