Some PRs related to 4.14 NE982 had been merged, I tried to test it with route and found the http headers couldn't be patch or edit to a route. Reported "Warning: unknown field "spec.httpHeaders"

4.14.0-0.test-2023-08-10-005149-ci-ln-5fii4tt-latest

1. create an route 
% oc get route
NAME            HOST/PORT                                                         PATH    SERVICES        PORT   TERMINATION   WILDCARD
unsec-server3   unsec-server3.int1.shudi-414g10.qe.gcp.devcluster.openshift.com   /test   unsec-server3   http                 None 
2. Try to patch the route with httpheaders
% oc patch --type=merge --patch='{"spec": {"httpHeaders": {"actions": {"response": [{"name": "X-Frame-Options", "action": {"type": "Set", "set": {"value": "aaDENYbb"}}}]}}}}' routes/unsec-server3
Warning: unknown field "spec.httpHeaders"
route.route.openshift.io/unsec-server3 patched (no change)
%  
3. Try to edit the route with the following:
  httpHeaders:
    actions:
      response:
      - name: X-Cache-Info
        action:
          type: Set
          set:
            value: "not cacheable; meta data too large"
      request:
      - name: Content-Location
        action:
          type: Set
          set:
