Bug 1850039

Description of problem:

When the OperatorHub is browsed, the Icons for custom Operators are not visible.
They get visible when the page is just scrolled down.

I check and saw that a request for the icon image is made just when the scrolling event get occurred.

The request is made to -
https://console-openshift-console.<ingress_wildcard_domain>/api/kubernetes/apis/packages.operators.coreos.com/v1/namespaces/openshift-marketplace/packagemanifests/<operatorname>/icon?resourceVersion=<operator_version>
