Android overscroll glow is janky on Nexus 7

Reported by jared.d....@gmail.com, Nov 12 2016 
Steps to reproduce the problem:
1. Open any site (e.g., arstechnica.com)
2. Fling scroll to the end of the page (up or down)
3. Notice the janky overscroll glow animation.

What is the expected behavior?
The overscroll glow animation should be smooth.

What went wrong?
Janky overscroll animation. See the attached trace, as the scroll ends there's a flurry of activity on the renderer thread, and the GPU thread bottlenecks briefly.

Did this work before? Yes 54.0.2840.85

I think every browser-driven animation regressed recently on M56, see also  http://crbug.com/661946 .  I'll bisect soon.
