Problem:

As of Jira 8.19, the Screens administration page uses the REST API to paginate and load the list of screens according to JRASERVER-67331: View Screens page load slow when there are many screens and workflows.

However, at the same time while loading information about screens, Jira also requests information about associated workflows. This particular part of the overall process also cause performance degradation depending on the number of workflows in the instance as discussed in the following bug report:

• View Workflow page load slow when there are many workflows.

Requested Functionality:
The request is to implement the lazy load functionality on the screens page - "/secure/admin/ViewFieldScreens.jspa" i.e. show only the first page at once.
