Issue 792908  has been merged into this issue.

Hi horo@, would you be able to triage this bug?

Mainly 'respond-to-same-origin-request-with-cross-origin-response.html' failed,

I think comment 2 is referring to the webkit layout test suite instead of content_unittests.

The failing test is RenderWidgetHostViewMacTest.ForwardKeyEquivalentsOnlyIfKey.  This test has been flaky for a long time across all Mac bots: https://test-results.appspot.com/dashboards/flakiness_dashboard.html#testType=content_unittests&showAllRuns=true&tests=RenderWidgetHostViewMacTest.ForwardKeyEquivalentsOnlyIfKey

Assigning bug to original test author, disabling test, and removing bug from sheriff queue.
