@cbiesinger: 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. Provided suspect through 'Chromium' bisect as unable to perform bisect using 'per-revision' bisect script 
2. Tried performing 'per revision' bisect on multiple Windows,Linux and Mac machines but unable to perform the same since getting error: "RuntimeError: We don't have enough builds to bisect". 

Thank you.
