Note: #183 was also for this test, but it was closed more than 10 days ago. So, I didn't mark it flaky.

When I ran this locally, it took 58609ms - there's a lot of prep that has to be done before the test starts - I suspect we're hitting timeout issues.

I'm going to close for now but see if it reopens - it's also passing on the impacted PR right now
