This is a regression issue broken in ‘M-59’ and using the per-revision bisect providing the bisect results,
Good build : 59.0.3064.0 (Revision : 462306)
Bad build : 59.0.3065.0 (Revision : 462712)

You are probably looking for a change made after 462413 (known good), but no later than 462414 (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.

@eustas : Could you please look into the issue, pardon me if it has nothing to do with your changes and if possible please assign it to concern owner.

Note : Unable to reproduce issue on Linux(14.04 LTS) OS since 'Panda Safe Web' extension doesn't function properly on Linux.

Thank you.
