jazzhsu@: 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. Unable to provide 'per-revision' bisect as it shows "We don't have enough builds to bisect" error message for above range. (tried on other 
machines but still getting the same error again)
2. Unable to perform Chromium bisect as 'File is not a zip file' error is seen.
3. Hence providing suspect manually.
Issue is also seen on Dev build #72.0.3626.14.

Kindly refer the screen cast for reference.

Thank You!
