Note: current WebKit nightlies match the Gecko/Trident behavior on the linked test case. We just haven't shipped the change in a Safari release yet. I don't have strong data on the compatibility impact of this specific change, but when we diverge from both Firefox and IE, it is rarely on purpose, and matching them has almost always fixed bugs, even if we didn't know it at the time.
