Steps to reproduce the problem:
1. Visit a web page.
2. Ctrl+click a link on the page.
3. Start two-finger scrolling with a touchpad.

What is the expected behavior?
The view scrolls from the current position.

What went wrong?
The view jumps immediately to the top of the page and then continues scrolling.

Did this work before? Yes I think in the previous major version (50.*)

Chrome version: 51.0.2704.79  Channel: n/a
OS Version: Kubuntu 16.04
Flash Version: Shockwave Flash 21.0 r0

This doesn't happen when I open the link using right click -> Open in new tab. Also, this doesn't happen when I scroll using a mouse wheel.
