Regression in 99th percentile of ScrollUpdate.Touch metric

Project Member Reported by nzolghadr@chromium.org, Jun 25 2018

Issue description

There seems to be a regression

https://uma.googleplex.com/p/chrome/timeline_v2?sid=636a485e8b9e42012cc2969f510efc70

in 99th percentile of Event.Latency.ScrollUpdate.Touch.TimeToScrollUpdateSwapBegin2 in this range:

https://chromium.googlesource.com/chromium/src/+log/69.0.3445.0..69.0.3447.0?pretty=fuller&n=10000

The breakdown metric Event.Latency.ScrollUpdate.Touch.BrowserNotifiedToBeforeGpuSwap2 also shows the same regression.
