Pranjali:

My change basically changes some strings on UI and therefore I doubt it's the cause. Also, I build the TOT on Linux, and I cannot reproduce your issue. Maybe it's only seen on Windows or Mac? 

BTW, how did you get the chromium bisect? If the cause must be one of them, then I would suspect is https://chromium.googlesource.com/chromium/src/+/30b891346bd02d47d1b6b9dd09afd81306b7ad07 since it has impact on NTP and claims to make something invisible, although I'm not sure about the details.
