geometry.open with "model": "new" cleared the model but kept the session's file path, so File > Save wrote the new model over the previous one. The path and the revision saved there (which document the session is) were not part of the undo state. A step now records the document when its command changed it: the new model is untitled and unsaved; undo restores the old file and its clean state, redo the untitled model (or the file it was saved to since).
