So far I have not been able to reproduce the timeout for this test, and will continue working through it tomorrow.

I have not been able to reproduce this timeout. I've ran though iterations up to 100000 times. I've ran as a test list, even running the test list through iterations up to 1000 times. I've ran the test in BigSur and Catalina. I've ran it as wk1 and wk2. I've also ran it as a full process, and in parallel (--child-process), as well as trying several different revisions, and I haven't reproduced the timeout.  

I have updated the test expectation to flaky (Pass Timeout) here:
