Chromium	59.0.3057.0 (Developer Build) (64-bit)
Revision	a9303533d7a58837b36689fdb39cbe88e7d5bf95
OS	Linux

What steps will reproduce the problem?
(1) Set your chrome window to half screen width. I'm on a 2560x1600 monitor so width = 1280 for me.
(2) Go to https://play.google.com/store/movies/details/Fantastic_Four?id=OVS_z4Ru1YY&hl=en and play the trailer video on that page.
(3) Toggle fullscreen on and then off.

What is the expected result?
Page doesn't scroll and shows the same content as before going fullscreen.

What happens instead?
Page scrolls to the bottom.

Look at the video in  issue 562100  and you'll see that the page scrolls down after exiting fullscreen mode. I was able to reproduce this on my workstation. Ignore the problem about right hand side being chopped as that is not reproducible by me or the reporter.

I wasn't able to reproduce this if my browser window width is full screen width (2560p). In firefox I was able to reproduce some scrolling but not as much as Chrome - it only scrolls a few lines down after exiting fullscreen. I don't know if this is an issue with the page or with Chrome.

Attached trace.
