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

Demo for current browser behavior:  https://software.hixie.ch/utilities/js/live-dom-viewer/saved/13966

#e and #g are of particular interest, as the unprefixed and prefixed variants differ.

I ran the same query but for `-webkit-background-size`:

| Row | client  | pages_with_background_size | pages_with_single_value_len_pct | pages_with_single_value_auto | total_pages | pct_pages_with_background_size | pct_pages_with_single_value_len_pct | pct_pages_with_single_value_auto |
