CDR: pointer event description vs. z-order

"The target element for pointer device events is established by first  
determining the most deeply nested child document which has content  
that intersects with the geometric (x,y) location of the event"

- This excludes z-ordering. Therefore it seems to claim that, for  
instance, a click on a portion of a parent document that overlaps  
included child content should go through to the child content. This  
is contrary to behavior of many current UAs.
