Docker-Desktop k8 cluster problems when port-forwarding to load balancer

I am running the simple deployment below (webapp with 5 replicas and a load balancer) in the single node Docker Desktop K8 cluster on Windows as host. The webapp simply serves a page that displays the hostname, so I can validate that the load balancer is balancing incoming traffic.

When I "curl" the load balancer from another pod within the cluster, it distributes the traffic as expected, resulting in different hostnames that I receive in the resulting curl response's content section.

Unfortunately, I am facing problems when I am "port-forwarding" traffic outside the cluster from my Windows host to that load balancer. I am using the following command to do so:

kubectl port-forward service/mywebapp-svc :80 

Now, I can access the webapp from a local browser, but it seems to always sending traffic to the same pod (even when I clear cache or use different browsers). Also, a curl from the Windows host to the forwarded port is resulting in the same pod receiving the traffic.
