Issue exist in windows as well

Able to reproduce the issue on windows 7 using chrome version 58.0.2989.0.but not observed the scroll bar on Mac 10.12.2.

Providing manual bisect because good and bad builds got from different milestones.

Manual bisect info:
=========================
Good Build:57.0.2987.0
Bad build:58.0.2988.0

Changelog got from Omahaproxy which is as follows:

sureshkumari@, can you please run per-revision bisect?

Thank you!

Performed per-revision bisect by increasing the bad revision which yielded all the good builds same as before. As a result of which CL generated would be a wrong one.

Hence, got the CL from omahaproxy by performing manual bisect.

Thanks..

This seems to be working fine on the latest canary(58.0.2998.0) of Windows-10 and Linux Ubuntu 14.04.

Hence adding the verified label.

allada@: Please close the issue if there is no further work to be done here.

Thank you!
