The unit test in title have been using fixed seed to mask flakiness. Suggested action:

  1. Evaluate whether the test is flaky without fixed seed. If not, remove seed. Else move to 2
  2. If test is flaky, determine whether it's an actual uncaught edge case. If so, fix the operator. Else move to 3
  3. If numerical instability is inevitable, adjust tolerance level appropriately.

Not reproducible on both CPU and GPU. I have re-enabled random seed for this test: #11958
