Looks like it's a xDS sequence issue. Sometimes, the clusters come before the listeners.

We had this issue before but it has been fixed in envoyproxy/go-control-plane#752 and envoyproxy/go-control-plane#801. However, it seems like there're still some edge cases that have not been covered.

keycloak_gateway-conformance-infra_80 was received at "2024-09-30T03:38:17.438Z", and the listener gateway-conformance-infra/same-namespace/http with the OAuth2 filter was received ast "2024-09-30T03:38:17.433Z",
