The metric that is shown as regressesing (in https://chromeperf.appspot.com/group_report?bug_id=836533 and https://pinpoint-dot-chromeperf.appspot.com/job/14ed5c2fc40000) is timeToFirstMeaningfulPaint.  Therefore, I think we should dupe this bug against  issue 836469  and continue the investigation overthere.
