Sorry to revert your CL, but it's blocking the CQ, so revert to get CQ rolling, then you can take your time investigating.

it is also flaky on other platforms as well (see  issue 841188 ).

 Issue 841188  has been merged into this issue.

Fixed and relanded in https://chromium-review.googlesource.com//1053597
