説明

The solution of top:-100%; and margin:1px 0 0; does not keep the iframe positioned in a viewable area at all times. If the target element is nested in an element with overflow: hidden and the target element has a negative top margin or a negative absolute positioned top the resize events stop working.

top: 0; z-index: -1 seems to fix the issue but I'm not sure what all the consequences are.
