I wrote up these "containing block" issues before I had noticed the recent
publication of the editors' draft.  The only change between what I was
looking at and the just-published editors' draft is that rule 4 (containing
block for position:absolute) changes "[If] the ancestor is inline-level" to
"[If] the ancestor is an inline box", which would appear to make it clear that
it's talking about box tree ancestry; but the change makes it all the stranger
that the text goes on to talk about first and last boxes that this ancestor
generates: as far as I know, boxes aren't considered to generate boxes.
