@dpapad: 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:
1.Tried per revision bisect on Windows ,Mac and Linux OS but unable to perform the same since getting "RuntimeError: We don't have enough builds to bisect" error 
2.Hence provided suspect through 'Chromium bisect'


Thank You
