			It seems like both BFC and IFC can have absolutely positioned children. It's a bit strange, but consider the following HTML: <html><body>foobar<img style="position: absolute"></body></html> In such a document, the <img> element is an absolutely positioned child of a block-level element (<body>) with no block-level children. An IFC is established for <body>, and needs to handle layout for <img>.
