mergegateway broken in 1.0.2

[Uburro]

Description:
when i have upgrade envoy gateway from 1.0.1 to 1.0.2 i saw that envoy gateway operator does not merge gateway anymore. And see a lot of deployment when i created kind: Gateway. Rolled back deployment fixed this problem.

Environment:
kubernetes: v1.27.3
Envoy Gateway 1.0.2

Also i see when merge gateway works correct label gateway.envoyproxy.io/owning-gatewayclass in deployment
When merge gateway does not work just

        gateway.envoyproxy.io/owning-gateway-name: spark-gateway-sparkcluster-e0tfrazvr7sang80t3
        gateway.envoyproxy.io/owning-gateway-namespace: sparkcluster-e0tfrazvr7sang80t3

it looks like merge gateway didnt kick in, any negative status in GatewayClass or Gateway ?

but EXTERNAL-IP assigned to kind: service

[Uburro]

intersting, when i have deleted all my gateway and deploy it again (in version 1.0.2) - all of them work ok. Where envoy gateway store metadata about do i need merged gateway or not? i see this one but it for pathing labels of deployemtn and services

Hi @Uburro, curious about your upgrade steps ?

Did you first remove existing EnvoyGateway ? and then reinstall it ? If is, then is related to #2637. The lots of deployment you saw, are probably got created right after the uninstall steps.

[Uburro]

Hi @shawnh2. I deployed through fluxcd in helm release controller. It similar helm upgrade -i ....
Do i need delete envoy gateway after that install int when i want to deploy new version of operator?
