Site isolation causes off by 1-pixel layout test

Project Member Reported by erikc...@chromium.org, May 17 2018

Issue description

Patch set 5 of this CL has a single test failure:
https://chromium-review.googlesource.com/c/chromium/src/+/1053882/5

Which is the site-isolation version of the newly added layout test. This difference goes away if the iframe's height is changed to 200. I've attached an image of the DOM difference.

[Note: This is not blocking me, I've just changed the iframe to have height 200 instead].

Thanks for the report!

foolip@: Would this be addressed by the work in  issue 667551 ?

I don't know yet, I haven't tried rebaselining anything yet, so don't know if 1-pixel offsets are a common type of change. Unassigning until known to be related.
