How to handle drag-and-drop to the desktop in Plasma 5?

[Weng Xuetian]

Just tried to debug it a little bit, looks like FolderModel::drop is
not called at all.

>From the observed visual behavior, plasmashell seems to takes the drop
as a new plasmoid request so FolderModel doesn't get the drop event.

Probably it is blocked by following code in desktop containment.
if (isFolder && event.mimeData.hasUrls)
