Description Jacob Uphoff 2020-03-04 14:00:19 PST

This test became a flaky failure after commit r257840

I was able to reproduce this failure by running the test in debug. It does not reproduce on r257839 but it does reproduce on r257840.

This is very suspicious. I am going check if it is a sim only failure.
