What steps will reproduce the problem?

This is a regression issue broken in ‘M-72’ and soon update other bisect info.
Good build: 72.0.3603.0
Bad build: 72.0.3604.0

Unable to provide 'per-revision' bisect as it shows "RuntimeError : We don't have enough builds to bisect..." error message for above range. 
Hence provided suspect through 'Chromium bisect'.

CHANGELOG URL:

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