[csswg-drafts] [css-anchor-position] Is it intended that `(justify|align)-items: anchor-center` doesn't apply to anchored abspos boxes with `(justify|align)-items: auto`? (#13514)

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

== [css-anchor-position] Is it intended that `(justify|align)-items: anchor-center` doesn't apply to anchored abspos boxes with `(justify|align)-items: auto`? ==
`anchor-center` was [explicitly added](https://drafts.csswg.org/css-anchor-position-1/#propdef-justify-items) to `(justify|align)-items`.
But these will never apply to abspos boxes, because `(justify|align)-self: auto` for abspos boxes [do not refer to](https://drafts.csswg.org/css-align-3/#valdef-justify-self-auto) `(justify|align)-items` at all:

> Behaves as [normal](https://drafts.csswg.org/css-align-3/#valdef-justify-self-normal) if the box has no parent, or when determining the actual position of an absolutely positioned box.

So it seems only relevant when we compute the hypothetical box, where it ends up becoming `center` (Since we're pretending to be static-positioned).

Wanted to confirm if this is the intended behaviour.
