The background images set on the root element will blend with an initial white backdrop. Instead, they should blend with the background-color of the root element, or, if no background-color is specified for the root element, background images should blend over an initial transparent backdrop. The spec states: Each background layer must blend with the element’s background layer that is below it and the element’s background color. Background layers must not blend with the content that is behind the element, instead they must act as if they are rendered into an isolated group.
