IIUC, this alert is about a performance change in the "Android Nexus6 WebView Perf" bot. My change titled "Remove supressNextClick JavaScript." only affects iOS, so assigning to zhelfins@ for investigation.

My change is exclusively within ChromeOS, reassigning to michaeldo to investigate.

It looks like neither of these CLs should be the cause because they are not changes which affect Android.

I've triggered a bisect according to instructions at http://g.co/ChromePerformanceRegressions, but (to me) it looks like this may be caused by a dip in the graph which then simply recovered to normal values based on the "all graphs" link in c#1.

📍 Couldn't reproduce a difference.
