While creating a LoadBalancer service with ETP:Local and monitors are enabled, the healtmonitor is first created and then unexpectedly removed.

As a result, the loadbalancer remained in PENDING_UPDATE status indefinitely.

OCP4.12.0-0.nightly-2022-11-07-181244 on top of RHOS-17.0-RHEL-9-20220909.n.0 with OVN-Provider and monitors enabled.
