"Installed operator  -  ready for use" is shown before all operand pods are shown Running

cert-manager operator bunddle 1.10.2-18

Always

1. Install cert-manager operator in OpenShift Console OperatorHub. Wait a moment. When the Console shows:
cert-manager Operator for Red Hat OpenShift1.10.2 provided by Red Hat      <tick symbol>

Installed operator  -  ready for use

Check operand pods immediately and repeately:
$ oc get po -n cert-manager

Given Console already shows "Installed operator  -  ready for use", "oc get po -n cert-manager" can show not all pods have been Running. Below command are run after Console already shows "Given Console already shows "Installed operator  -  ready for use":

i.e. still needs wait one or more minutes after Console already shows "Installed operator  -  ready for use", all pods are Running, as above shows.

Given Console already shows "Installed operator  -  ready for use", "oc get po -n cert-manager" should show all pods have been Running. Otherwise Console should continue show it is installing, instead of showing "Installed operator  -  ready for use" which can confuse users.
