Changelog entry

This is failing almost all the time now:

We should get this fixed as it's adding time to every review (needing to check to make sure this is the only test that's failing).

If there isn't an immediate solution we should ignore this test, since we already are, but then at least we can see the test run as green and immediately trust it during code review.

Un-assigning incase anyone can get to this before next week.
