KDE Plasma 5 has the ability to have separate windows for file copying and similar tasks if you uncheck the "Track file transfers and other jobs" option in notification settings and the "Show progress and status information in task buttons" in task manager settings. However, when Latte Dock is opened it seems to ignore such settings and it will prevent separate windows for this types of tasks from appearing; there is a similar option in Latte called "Show progress information for tasks" but unchecking it has no effect. If Latte Dock is disabled, Plasma will start to show the separate windows as expected.
