Steps to Reproduce:
Try to type rapidly into the "Homepage Title Format" field in the squarespace admin console with ToT WebKit.
Uhh, if you follow the steps to reproduce, you see flashing. Because we're scrolling out of view for one frame.

> + if (newScrollPosition == scrollPosition())
In Safari Mobile, when the page loads, is the scrollPosition() already at (0,0), or is it at some other value?
If it starts off at (0,0), this change stops window.scrollTo(0,0) from hiding the URL bar. window.scrollTo(0,1), would be unaffected.
Any information you can provide here would be very helpful, especially with respect to https://bugs.webkit.org/show_bug.cgi?id=107026
