@tock-ibm Could you take a look?

[denyeart]

@tock-ibm I had to re-open this issue since we are still seeing frequent failures with this test, e.g.
https://productionresultssa0.blob.core.windows.net/actions-results/e60a1a69-df30-441c-b45c-e70884d32d7f/workflow-job-run-b8245a8d-c8fe-58cd-5361-3fdfc2c073c3/logs/job/job-logs.txt?rsct=text%2Fplain&se=2024-05-09T18%3A56%3A28Z&sig=EN%2BLghkEScQ5xV0A4Cn8yryFiiMSCztG9LDn3Gx6N2U%3D&sp=r&spr=https&sr=b&st=2024-05-09T18%3A46%3A23Z&sv=2021-12-02
