I just ran the test on the latest version of IE10 Preview and it does render the positioned elements on drag (tested: position: relative, absolute, fixed and nested). The latest preview available on Windows 7 didn’t, however. 

Based on the size of the drag’s preview, it seems that positonned elements are not taken in consideration when calculating the bounding box of the selection, as expected. 

However, the behavior of 3D transforms is not fully consistent. They are rendered on all non-positionned elements, but are not rendered by default on positionned elements; however they are if the element has a non-positionned ancestror or sibling which has a 2D or 3D transform applied to it, but this could have been fixed since then.

All in all, this seems pretty consistent with the specced behavior.

  Do you draw things like positioned children whose positioning root is
  an ancestor of the drawn element?


Yes. So do Chrome and Opera, it seems.
