I think what we want here is to define some new term and use that instead of
"containing block".  Like call it "transform parent", and say that the
transform parent of an element is the nearest transformable ancestor if the
element's position is relative or static, and the nearest ancestor with
non-static position if the element's position is absolute, and the nearest
ancestor that either is the root element or has a transform applied if the
element's position is fixed.  All uses of "containing block" in the spec should
be reviewed to see if they deserve to be changed.
