Marked as flaky in http://trac.webkit.org/projects/webkit/changeset/203757
I believe this was addressed by: https://webkit.org/b/160534 The specific assertion was removed, and code changed to better handle this area. Note the expectations are only for El Capitan, all future releases should be running the test just fine.
