That one seems to be a harness issue during the "test-verify" testrun process.

The log is here:
https://taskcluster-artifacts.net/aBa71QnzTce7CWoawaeXLg/0/public/logs/live_backing.log


It trips over "NoSuchWindowException: Browsing context has been discarded" while trying to run the test 10 times.  I'm guessing it might be intermittent?
