Service Mesh sidecar injection not working reliably

Description of problem:

envoy sidecar is not injected into Pod(s) reliably when ossm resources are created in a single YAML file. but things are working as expected when those resources are created individually.

How reproducible:

100%

Steps to Reproduce:

• install services mesh operators which are required.
• create smcp resource
• create the smmr and deployment by below YAML

apiVersion: v1
kind: Namespace
metadata:
  name: test
—
apiVersion: maistra.io/v1
kind: ServiceMeshMemberRoll

  name: default

apiVersion: apps/v1
kind: Deployment
metadata:
  name: centos8
  namespace: test
spec:
  progressDeadlineSeconds: 600

    spec:

          imagePullPolicy: IfNotPresent
          name: centos8
          args:
            - sleep
            - inf
          resources: {}
          terminationMessagePath: /dev/termination-log
          terminationMessagePolicy: File
      dnsPolicy: ClusterFirst
      restartPolicy: Always
      schedulerName: default-scheduler
      securityContext: {}
      terminationGracePeriodSeconds: 30

Actual results:

 oc get po
NAME                      READY   STATUS    RESTARTS   AGE
centos8-d74994b68-fzpfz   1/1     Running   0          29s

 oc describe po | grep -i container | grep -i created
 Normal  Created         29s   kubelet            Created container centos8

oc delete po centos8-d74994b68-fzpfz
pod "centos8-d74994b68-fzpfz" deleted

oc get po
NAME                      READY   STATUS    RESTARTS   AGE
centos8-d74994b68-8sczg   2/2     Running   0          78s

oc describe po | grep -i container | grep -i created
Normal  Created         71s   kubelet            Created container centos8
Normal  Created         68s   kubelet            Created container istio-proxy

Expected: envoy sidecar is injected reliably into Pod(s) when the Pod(s) are created
