Re: [csswg-drafts] [css-backgrounds-4] Initial value of 'background-position-y' should be 'top' (#1208)

Thanks. Indeed, resolving the writing mode at specified value time seemed problematic to me. 

Other logical properties seem to be mostly defining distance values, not a position like `background-position`, `mask-position`, or `scroll-start`. The latter has [`scroll-start-block|inline`](https://drafts.csswg.org/css-scroll-snap-2/#propdef-scroll-start-inline) defined with `auto` as its initial value but there is no associated definition. Shorthand encompassing both flow-relative and physical properties should map to their physical sub-properties after their flow-relative sub-properties, therefore the initial value of the latter will not affect the formers. But anyway, `0%` is fine.
