The store is the data model; the TreeView displays exactly what is in
the model.  So you are rearranging the rows in the store itself.

If you want to rearrange the order without reordering the rows in the
store then you need an intermediate model that will read from the store
and reorder the rows on-the-fly using some other data structure.
