Inline boxes flow around floats, including floats that are
"anchored" inside the inline box itself.

Because 4 of the 9 rules in
http://www.w3.org/TR/CSS21/visuren.html#float-position that describe
how to position floats mention containing blocks?

An inline box never forms the containing block for a float.  Only a
block box does.  See section 10.1.

However, the anonymous block box formed as described in 9.2.1.1
(when an inline element contains a block box) is a block box, and
can establish a containing block for a float.  (There's an exception
in 9.2.1.1 only for percentage heights.)
