After configuring remote-write for UWM prometheus named "user-workload" in configmap named user-workload-monitoring-config, the proxyURL (same as cluster proxy resource) is not getting injected at all.

4.16.4

100%

1. Configure proxy custom resource in RHOCP 4.16.4 cluster
2. Create user-workload-monitoring-config configmap in openshift-monitoring project
3. Inject remote-write config (without specifically configuring proxy for remote-write)
4. After saving the modification in  user-workload-monitoring-config configmap, check the remoteWrite config in Prometheus user-workload CR. Now it does NOT contain the proxyUrl. Example snippet:
==============
apiVersion: monitoring.coreos.com/v1
kind: Prometheus
metadata:
[...]
  name: user-workload
  namespace: openshift-user-workload-monitoring
spec:
[...]
  remoteWrite:
  - url: http://test-remotewrite.test.svc.cluster.local:9090    <<== No Proxy URL Injected 

UWM prometheus CR named "user-workload" doesn't inherit the proxyURL from cluster proxy resource.

UWM prometheus CR named "user-workload" should inherit proxyURL from cluster proxy resource and it should also respect noProxy which is configured in cluster proxy.
