Yes, that's a better way to phrase what I was trying to say.

Not sure about floats.  Abspos shouldn't be affected.

Yeah, I don't think we need to worry about ::inline-ellipsis, but we
can always address it later if we decide we care.  The point is that
the styling needs of block ellipsises appear to be more complex than
inline ones.

Not at all!  Your intuition is probably just biased by the fact that
the 2.1 pseudo-elements are all completely generic, so we don't apply
*anything* to them.

The ::marker pseudo has several properties specified on it in the UA
stylesheet, because it's meant for a specific purpose, and I've made
most of its special abilities usable in general through some new
properties.  ::block-ellipsis is similar - it has a specific use, and
we can actually give good defaults for this usage.
