Description

The test is not flaky on 5.0 - https://app.circleci.com/pipelines/github/ekaterinadimitrova2/cassandra/2590/workflows/47dedf52-87fd-4178-bc89-d179e58b6562
But it is significantly flaky on trunk - https://app.circleci.com/pipelines/github/ekaterinadimitrova2/cassandra/2591/workflows/1150aab2-4961-4fe3-a126-b96356fdb939/jobs/49867/tests
