  https://chromium.googlesource.com/chromium/src.git/+/48c12fb9154ff9177f9a9a5e6ff2d035896d7a7b

commit 48c12fb9154ff9177f9a9a5e6ff2d035896d7a7b
Author: Mitsuru Oshima <oshima@chromium.org>
Date: Wed Aug 30 00:26:36 2017

Update the backdrop when the widget state changes.

Currently the window state is updated outside of commit so
and we need to update upon the state change request from
client.

This should be changed when we move the window state change
into commit.

CL introduces parameterized test for bounds mode.

R=reveman@chromium.org, mtomasz@chromium.org
BUG= 760188 
TEST=covered by unittest, also teted on device.
