This way we always serialize in the shortest form, and take less space. This is useful because when serializing uncomputed values we'd like to compare to the initial value to avoid serializing parts of a shorthand, but with the existing implementation we would generate always a second keyword, which means that we'll never match it. This also matches Chrome and WebKit, incidentally, so I'm pretty confident the behavior change when serializing specified style is web-compatible.
