It's unclear when this regressed, who can investigate?
Looking at recent changes, a rollout <http://trac.webkit.org/changeset/163655> seems like the only one that touched this code.
Alexey Proskuryakov
The rollout is definitely the culprit, because the test was also asserting before those changes, and started to assert again once they got rolled out.
