Groups beyond first page can show no users in group management pop-up

[SimonDmz]

For an application with more than 10 management groups
Steps to reproduce :

• {sugoi-ui-url}/realm/{your_realm}/applications/{your-app}
• Select page 2 below the main table
• Click on the Gear icon of a group
• Group management modal pop-up with no users in right half (expected behavior : display users id)
  => when the app get response for user search in left half, all users are displayed with the ADD icon ➕ as if they don't belong to the group

Hints :
Network dev-tool show the 10 api calls to {sugoi-api-url}/realm/{your_realm}/applications/{your-app}/groups/{group-N}, but when changing page, there are no calls to api for newly displayed groups.
Sometimes the displayed users id are from another group (maybe worthy candidate for distinct issue)
