Weird, new javascript & tabs problem after Safari update

Updated to 10.5.8 from 10.5.4 and Safari 4.x came along for the ride.

Now Safari will not resize/move its window with javascript anymore if 2 or more tabs are open in said window -- never had this problem before with any older version of Safari.

Here's some example javascript that you can make bookmarks and click: (but won't work if there's multiple tabs open)

javascript:self.moveTo(300,15);self.resizeTo(1055,915);
