        <pre>IOS 9 - Safari for iPhone

Steps to reproduce:

1.) Run Safari for iPhone on IOS 9
2.) Open a long page
3.) Scroll down to the end/bottom of the page until you receive a rubberband effect
4.) Do immediately a further swipe so that the toolbar at the bottom appear and the page receives a further rubberband effect.

Actual: The toolbar at the buttom appears but the rubberband effect of the page stutters. 

Expected: The toolbar should appear and the page should have a smooth rubberband effect.

This is a regression. It works fine with Safari on IOS 8.

If you have any question, please let me know.

Thanks in advance.</pre>
