Re: [csswg-drafts] [css-backgrounds] Always serialize 'background-size' and `mask-size` as two values (#7802)

What should `background-size: auto` serialize to? currently in webkit it serializes to `auto` rather than to `auto auto`.
I think this is fine, but it's different from the resolution of "always serialize to two values". It's more like "serialize to two values if they are not equal, even if the second one is the default".

@nt1m WDYT?
