    Looks like this issue is flaky. 😟

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

    A human should fix and close this.


    When run at the same commit (5e50beb), this test passed in one build (Build Status, Sponge) and failed in another build (Build Status, Sponge).

  4. added
    priority: p2Moderately-important priority. Fix may not be included in next release.
