15% regression in power.trivial_pages / energy_impact / TrivialAnimationPageSharedPageState

Project Member Reported by shrike@chromium.org, Jun 1 2017

Issue description

Chrome Version: 60.0.3091
OS: macOS 10.12

Works out to a 4% regression on the snapshot of the realworld apple.com home page. Curious what caused it.
