Description
Dragging a tree node hangs if the node is a big adapted object. I could fix that by replacing this line https://github.com/enthought/traitsui/blob/6bb4f756eb4a73e7e1ae1feec8edba5b8fe12141/traitsui/qt4/tree_editor.py#L1577 with ` md = PyMimeData(drag_object, pickle=False)`. Hanging (not indefinitely) wasn't the only problem. Does this fix make sense? If it is, can we make this optional perhaps in the tree editor factory?
