Text drag/drop: Creates a composite undo/redo if source and target are the same morph/editor.
Note that drag-dropping text between text morphs (i.e. windows or panes) is not affected. You have to focus and undo/redo separately.
Do-it the following example to drop text from a source that does not use the TextMorph/TextEditor mechanism:
ActiveHand grabMorph: (TransferMorph withPassenger: 'Hello, World!' asText from: nil).
