Steps To Reproduce

Steps to reproduce the behavior:

Create an imperative way empty tenant TCL/TMOS auth partition tenant_1 { }
Create an imperative node TCL/TMOS node definition

ltm node /Common/SharedNode1 { address 192.168.0.4 } ltm node /Common/SharedNode2 { address 192.168.0.5
} ltm node /tenant_1/AppNode1 { address 192.168.0.6 } ltm node /tenant_1/AppNode2 { address 192.168.0.7 }

Submit the following declaration using POST to https://192.168.250.2/mgmt/shared/appsvcs/declare/tenant_1/applications

        ]
    }

}
}

Check node list in Common and tenant_1 partition nodes from tenant will be deleted

Expected Behavior

I would expect that posting declarations per-ap will not touch any other object which are stored in tenant_1 directly and change only in scope of app folder e.g /tenant_1/app1

Actual Behavior

Nodes that are stored directly in tenant folder are deleted by per-ap declaration in that case AppNode1, AppNode2
You can no refer in pool to node object stored in the tenant e.g.

  ....
   "members": [
                {
                    "addressDiscovery": "static",
                    "servicePort": 80,
                    "bigip" :"/tenant_1/AppNode1",
                    "shareNodes": true
                },
  ...

return error
"code": 422, "message": "declaration failed", "response": "01020036:3: The requested node (/tenant_1/AppNode1) was not found.", "host": "localhost", "tenant": "tenant_1",
