I noticed that when I return from the "Edit User Roles" tab to the Users screen using the back arrows, the pagination disappears.
Log in as administrator.
Go to Administration > Users.
Click the "Roles" button.
Go back to the Users page using the back arrow.
The page has no pagination.
The Pagination shouldn't disappear.
NOTE: This issue doesn't appear when we use the "Cancel" button on the Edit User Roles screen.
