Float Escapes its Parent's Content-Edge When Parent is Relatively Positioned
In the text below, an image is floated with float: left. In Mac IE, it is positioned above it's parent, but it should not be.
The w3c float specification specification states:
A floating element's top may not be higher than the inner top of its parent.
Floated element positioned doen not account for
of parent element.
The image is offset by
-20px. It should be positioned within
its containing block.
