seems this testcase was successful at the latest attempt, it's not clear why it failed here, and not able to reproduce it locally.
do we have any log to check for the root cause in the CI? or we can add one for later investigation.

I don't but I have a hunch the flakiness is related to transient issues with the docker calls and the GitHub runner.

This is related to #5325 in that that PR didn't replace all instances of the testutils.Setup with the corresponding teardown.

Here's a PR with the fix: #5950
