There are a couple of things that went into this: - We now calculate the intrinsic width/height and aspect ratio of <svg> elements based on the spec algorithm instead of our previous ad-hoc guesswork solution. - Replaced elements with automatic size and intrinsic aspect ratio but no intrinsic dimensions are now sized with the stretch-fit width formula. - We take care to assign both used width and used height to <svg> elements before running their SVG formatting contexts. This ensures that the inside SVG content is laid out with knowledge of its viewport geometry. - We avoid infinite recursion in tentative_height_for_replaced_element() by using the already-calculated used width instead of calling the function that calculates the used width (since that may call us right back again).
