Demo of problem

Two elements on a page, the first is an <hr> with a border-color of rgba( 255, 255, 255, 0.5 ). The alpha number (the last) can be anything other than 0 and 1, I believe.

The second element is a <p> or <div> with a background-color of #ffffff.

The second element renders with an incorrect black background in Safari 5.0.6 (5533.22.3) and Chrome 13.0.782.215. It should be white.

Simple demo attached.
