commit 36670a32fb24c76cbba10511911f17339204d2c9
Author: Philip Jägenstedt <foolip@chromium.org>
Date: Thu May 17 12:42:08 2018

Roll in new version of WPT tools

https://github.com/w3c/web-platform-tests/pull/10985 changed lint.py
and wpt-importer is now failing because of it:
https://ci.chromium.org/buildbot/chromium.infra.cron/wpt-importer/17652

chromium.patch did not apply cleanly, so the changes had to be rebased
on the new wpt version.	This was much easier within the	wpt repo
itself, so the patch is	changed	to apply within	the repo.

fhorschig@: Since you're poking at other cookies tests, would you be interested in poking at these as well? It looks like the following tests are the ones which are causing issues:

commit caa764f5fe713b39ee59ce279dbeb22c9b88a0bd
Author: Mike West <mkwst@chromium.org>
Date: Fri Aug 17 10:45:29 2018

Fix cookie prefix tests.

The layout tests aren't testing much at the moment, as they're never
served over HTTPS. This patch creates `.https` versions of the tests
and reworks them to actually exercise the behavior of `__Host` and
`__Secure` cookie prefixes.

'content_shell' should allow third-party cookies in layout test mode.

Several cookie tests are failing under content shell because it defaults
to blocking third-party cookies. We should invert that default in order
to correctly run web platform tests.
