Comment 5 by liber...@chromium.org, May 22 2018 

seems like this is specific to this device.  the other macs aren't affected:

not sure what's different between them.

+ellyjones@, are you aware of something specific to this mac that could explain this result?

The bot no longer exists, we can't reproduce this locally and the current mac bots do not reveal something wrong: https://chromeperf.appspot.com/report?sid=81ff8378d2f03bace96c9ce06ce823903a52f0e82568c1ca6449cafa69875fc1&start_rev=568963&end_rev=577152
