@wangxianzhu: Could you please check whether this is caused with respect to your change, if not please help us in assigning it to the right owner.

Note : 
1) Providing suspect using chromium bisect script because unable to perform bisect using 'per-revision' script.
2) Tried performing 'per revision' bisect on multiple Windows and Mac machines but unable to perform the same since getting following error:
   - Error message on Mac OS:[Errno 2] No such file or directory error message
   - Error message on Windows OS: RuntimeError: We don't have enough builds to bisect.

Kindly refer the attached screen-cast.

Thank you..!
