Comment 25 for bug 744580

My bug 552707 patch is waiting final review of smaug. The patch has been already passed ui-review and roc's first review. And even if this patch would be landed first, I needed to backout of this change and need to change my patch for scrolling body on its edge. Therefore, I'd like you wait bug 552707 fix and recreate your patch based on my patch. If so, the behavior will be standardized on all situations.
