window-slot-dnd: Ignore data not received on hover
Sometimes, after having called gtk_drag_get_data() on ::drag-motion, we
only get the data after ::drag-leave.
This is fine if the ::drag-leave is followed by ::drag-drop. Otherwise,
as ::drag-leave is responsible for cleanup, data arriving afterwards is
leaking into the next time content is dragged hover the widget, even if
the dragged content is no longer the same.
Instead, keep track of the hover status and don't save data that's no
longer relevant.
