Automatic update from web-platform-tests fix background-position-xy serialization for right/bottom offsets Make the implementations of CSSValueFromComputedStyle for background-position-x/y return correct values when three/four-value syntax is used with background-position. Since these properties only support single-value syntax, positions from the right or bottom will use calc() values if they result in mixed lengths and percentages when converted to be from the left/top. This is not the canonical form in the css-backgrounds-4 spec proposal, but does not require changes to the parser. Add a reftest (passes without patch) for three/four-value background-position syntax (there is currently only a manual test). Add another version of the reftest (fails without patch) which takes the above and attempts to write back the computed values of background-position-x/y. This is done in preparation to make transitions use normal keyframes which require round-trip serialization of all transition properties.
