[csswg-drafts] [css-align] align-content and scroll coordinates (#9807)

fantasai has just created a new issue for https://github.com/w3c/csswg-drafts:

== [css-align] align-content and scroll coordinates ==
In https://www.w3.org/TR/css-align-3/#overflow-scroll-position we write:

> None of this changes how scroll coordinates are assigned: the origin is still where it would be in a [start](https://www.w3.org/TR/css-align-3/#valdef-self-position-start)-aligned container, it just might be initially positioned outside the [scrollport](https://www.w3.org/TR/css-overflow-3/#scrollport).

Wrt scroll coordinates, if we are referring to `.scrollTop`/`.scrollLeft`, I noticed when testing `flex-flow: row-reverse` etc that the initial scroll position corresponds to zero, so I think we should adjust the spec for alignment to be consistent with that: the initial scroll position corresponds to zero, even if that position is scrolled to the writing-mode–relative "end" of the scroller.
