CanvasBase constructs the backing store as DisplayList::ImageBuffer in some cases - DisplayListDrawingEnabled is about render layer backing stores being display listed - Context2D cannot support display lists, as putImageData is not supported and getImageData would need to flatten the list - CanvasRenderingContex2DBase already has a setting to record display lists for CustomPaintCanvas
