When an element with 'fixed' positioning is within a container that with either 'fixed' or 'absolute' positioning and with 'overflow' anything but 'visible', the inner element is not rendered if it is positioned outside the boundaries of the container when a third positioned element is underneath either of them, and has a lower z-index than the container.
