Description Mark Rowe (bdash) 2015-03-02 18:26:00 PST 
After updating to TOT WebKit today I've noticed some strange behavior when scrolling. The two issues I've seen are the page not allowing me to scroll to the bottom, and the page being scrolled past the bottom. I bisected them to the range r180901 - r180906, which suggests r180902 as the likely cause.

Steps to reproduce:
1. Load <http://www.reddit.com/>.
2. Press Cmd-+ twice to zoom in.
3. Scroll to the bottom of the page using the trackpad.
4. Press Cmd-0 to reset the zoom level.
5. Scroll downwards using the trackpad.

This typically results in scrolling well past where the end of the page has been. I've also seen it end up with the page scrolled slightly above the bottom, but with the page rubberbanding rather than scrolling to the bottom.
