To replicate this bug, produce the following structure:
position: relative; and no height specified.display: block and a specified width
that is not positioned.If the specified with is not a percentage, then the absolutely positioned element
will disappear when the window is horizontally resized. If the specified width is
a percentage, it will disappear as the window is rezized, but reappear when it is resized.
This has been tested in IE6/Win.
