Not too concerned about this if it is limited to the one device. Will check again on Monday.

Offline, we decided that Yining is going to figure out out whether it is an infrastructure/device problem or a real regression in Chrome.

I rerun the test and verified on the prior build 59.9.3055.0, this issue NOT repro. Power usage on 59.0.3055.0 is normal. 
I will watch it on Monday again but almost certain it is a product bug.

Looks like it dropped back to 6.1 for 1080p60fpsVP9: https://av-analysis.corp.google.com/#/custom-page/2/Video%20Stack/16

Also dropped back down on windowed as well: https://av-analysis.corp.google.com/#/custom-page/2/Video%20Stack/19
