+dtu, another case of confusing UI for try jobs in #6 and #7.

For clarity, the metric shown in the graph that "couldn't reproduce a difference" is success rate: the benchmark ran correctly 100% of the time in both runs. To dig into the performance metrics, you'll need to look at the results by clicking "Analyze Benchmark Results" link:

#6: https://pinpoint-dot-chromeperf.appspot.com/results2/15d31f7d440000
#7: https://pinpoint-dot-chromeperf.appspot.com/results2/13ccd6ed440000

We're working on making it show the right metric.

If you click the "+" on the bisect job result page (from comment 3) it will show the right metric. If you click the "+" on the jobs listing page, it will run without a specific metric.

Fixes a mistake in the refactoring https://crrrev.com/c/965863.

other regressions as it affected scroll.
