istioctl uninstall with files is broken

Bug Description

Currently, I'm installing the Istio using a custom file with istioctl install -f custom.yaml. When I execute istioctl uninstall -r revision, the components are removed as expected, but this command removes all resources in a specific revision.

When I try to execute istioctl uninstall -r revision -f custom.yaml to remove the actual overlaid IOP resources, only Istiod is removed. The CNI and ztunnel, which were installed with istioctl install -f custom.yaml, remain in the cluster.

The expected behavior is that the uninstall command can correctly clean up the resources specified in my overlaid IOP file.

To reproduce:

 istioctl install -f out/yamls/overlay.yaml  
This will install the Istio 1.21.0 "ambient" profile (with components: Istio core, Istiod, CNI, and Ztunnel) into the cluster. Proceed? (y/N) y
