[css-align] normal alignment doesn't really behave as stretch for non-replaced abspos with auto insets #11215
Description
https://drafts.csswg.org/css-align/#justify-abspos
For replaced absolutely-positioned boxes, the normal keyword behaves as start.
For all other absolutely-positioned boxes, normal behaves as stretch.
https://drafts.csswg.org/css-align/#align-abspos
For replaced absolutely-positioned boxes, the normal keyword behaves as start.
For all other absolutely-positioned boxes, normal behaves as stretch.
However: https://drafts.csswg.org/css-position-3/#abspos-auto-size
If its self-alignment property in the relevant axis is stretch
Or if it is normal and the box is non-replaced, not a table wrapper box, and has no auto inset in the relevant axis
Its automatic size is its stretch-fit size.
Otherwise
Its automatic size is its fit-content size.
So normal can't be behaving as stretch if they affect sizing in different ways.

I think https://drafts.csswg.org/css-position-3/#abspos-auto-size needs to be removed.
And then, https://drafts.csswg.org/css-align/#justify-abspos and https://drafts.csswg.org/css-align/#align-abspos should resolve

I did the opposite and made css-align-3 defer to css-position-3, which I think is a better way to handle this. Lmk if this works for you @Loirooriol :
