Jenkins Kubernetes plugin proxy

Jenkins setup: Upgrade Jenkins from 2.361.1 to 2.479.3
My jenkins container (version 2.361.1) has http proxy set in JAVA_OPTS.
The kubernetes plugin is connecting to 10.96.0.1. Kubernetes was not using java proxy settings.
I upgraded recently to jenkins version 2.479.3. Kubernetes plugin is not able to connect to 10.96.0.1 anymore. I had to set noProxyHosts to 10.96.0.1 in the JAVA_OPTS for the connection to go through. It seems the kubernetes plugin is now taking the JAVA_OPTS proxy setting.

Can someone please point me to what has changed.

Also, I think this change is from 2.440.1 LTS version. HTTP Proxy Configuration page is moved from Plugins Manager to Configure System in this LTS version. Is the Kubernetes proxy change related to HTTP Proxy Configuration page been moved somehow?
