I have seen this test fail for an unrelated PR (dependency upgrade):

@tnqn could this be related to recent change which affected the reconciliation logic?

This is the link to the failed workflow: https://github.com/antrea-io/antrea/actions/runs/7199573923/job/19611559921?pr=5790

@antoninbas thanks for reporting it. Yes, it's related to the recent change. #5798 should fix it.
