fixes background-size tests for two values serialization (#49388)
- Update background-332.html
- Update background-size-001.html
This is fixing some WPT tests related to background-size results
being serialized as two values, which is the new behavior of WebKit.
Some tests currently contradict themselves on WPT.
http://wpt.live/css/css-backgrounds/background-size-001.html
https://wpt.live/css/css-backgrounds/parsing/background-size-computed.html
So this PR makes it uniform and changes the expectation files.
This is dependent on a resolution from the CSS WG about the two values system.
