Steps to reproduce:

Inserted a form input element with a box-shadow and a div within a div on a page. The div within a div (which is transparent) has its margin set to -11px and appears on top of the input's "box shadow".

Actual results:

When I change the div's zIndex the div within a div inherits a background color and covers the box shadow.

Expected results:

The div within a div should remain transparent.
