persist cancels move

If i have a node that i fetch from the repo using $dm->find()

If i change an attribute in it.
Then i call $dm->move() on it

Then i call $dm->flush().

It will work.

However if i call $dm->persist() on the node (that i already fetched from $dm->find()) and then call $dm->flush()
The $dm->move() won't occur, it will be cancelled, but the attribute i changed will still be updated.
