Steps to reproduce: 1. Go to http://www.apple.com/ 2. Hit the green "zoom" button at the top left of the Safari window, or simply adjust browser window width manually until the edge of the MacBook Pro photos are slightly off the edge of the screen. Expected results: As soon as anything goes off the edge of the screen as the browser window is made thinner, horizontal scrollbars should appear Actual results: You can have a certain amount of the images hidden before the scrollbars appear. Tested in r38297 on 10.5.5 on a MacPro. Note, this is not a regression from 3.1.2, though I haven't tested any earlier releases than that.
