Note: #597 was also for this test, but it was closed more than 10 days ago. So, I didn't mark it flaky.

Looks like this issue is flaky. 😟

I'm going to leave this open and stop commenting.

A human should fix and close this.

I see the similar behavior in tests which use datastore emulator. Tests are failing for the during Cloud Build pipeline run.
