This is the look that Yahoo! tested for many months prior to the release of Safari 4.0. In beta, it did not work particularly well with Safari 3.0. However, it worked very well with Firefox and Safari 4.0. There may have been an imperceptible tweak a few weeks ago, but the basic look and feel have been around for quite a while. So, if you are waiting for Yahoo! to work out a problem that you are having, you may be waiting a while.
