When a div has style "overflow:auto" and has content more than it can fit, left_clicking mouse on the <div> should set keyboard focus to the <div>. Scrolling using keyboard up and down arrow keys should scroll the div and not the main page that contains it.
1)Play any video @ youttube
2)Click on the div which shows related videos
3)press Keys "up" or "down" arrown
4) Safari scrolls main page instead of the div.
Works for me with a local debug build of WebKit r25149 with Safari 3 Public Beta v. 3.0.3 (522.12.1) on Mac OS X 10.4.10 (8R218).
May be a Windows-only issue.
I've checked the reported issue using the latest Webkit r30236 for Windows and the latest beta of Safari. Everything works correctly. So WORKSFORME
