Description Tim Nguyen (:ntim) 2022-11-13 23:10:51 PST

The old code was collapsing background-position-x/y into background-position.
It is not needed anymore, as returning true in canUseShorthandForLonghand for background-position has the same effect.

Test: fast/css/background-position-serialize.html
