Seems that the added test is flaky: https://github.com/Kong/kubernetes-ingress-controller/actions/runs/7178831047/job/19547840672?pr=5320. @czeslavo Do you think it is a good way to fix in this PR, or create another issue and fix it later?

I cannot see this PR adding any new test so I think it's fine to fix it separately. 🤔
