This is regression issue broken in ‘M-71’ and below is the bisect info:
Good build: 71.0.3543.0 (Revision: 588719)
Bad build : 71.0.3544.0 (Revision: 589076)

You are probably looking for a change made after 588740 (known good), but no later than 588741 (first known bad).

Narrow Bisect info:

Suspect: r588741 ?

@sweilun: 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. Tried performing 'per revision' bisect on multiple Mac, Windows and Linux machines but unable to perform the same since getting following error: 
(a) Error message on Windows and Linux OS : Unable to find locale data files 
(b) Error message on Mac OS:[Errno 2] No such file or directory error message.
   Hence providing suspect from chromium bisect.

Thank You!
