Using the per-revision bisect providing the bisect results,
Good build: 62.0.3165.0 (Revision: 488877).
Bad build: 62.0.3166.0 (Revision: 489161).

You are probably looking for a change made after 489098 (known good), but no lat
er than 489099 (first known bad).

CHANGELOG URL:

The script might not always return single CL as suspect as some perf builds might get missing due to failure.
