Tree leaf drag to bottom folder

Question

Hi !
With the following code, it seems impossible to drag leaf
"rio" (for instance) and drop it as the last child of "Europe" when
leaf "Spain" is expanded.
The only thing possible is to drop it as a child of "Spain"
or as a new and last root leaf.
This does not seem to be normal as you could drop "rio"
between "Spain" and "England", hence as a child of "Europe"
Thanks !

Not without changing the source code, which only Apple have access to.
