This has multiple benefits: - It makes DLBI detection of background-position changes work for buttons. - It makes background-attachment: fixed work for button backgrounds. - It allows the willPaintBorder optimization to be used for button background drawing, which reduces the background clip to not overlap with opaque borders. The willPaintBorder optimization requires a change to the reftest 611574-2.html. This reftest compares backgrounds to inset box shadows. Box shadows those don't have a willPaintBorder optimization, so we'd get different results due to the borders - inset box shadows will bleed through the rounded corner anti-aliasing of the border, backgrounds won't any more. So we just turn off button borders and cover the outer edges of the borders with an outline in that reftest. MozReview-Commit-ID: Lvx2p5szjw7 *** Cover the antialiasing in 611574-2.html with a black outline.
