python: can't close a 2nd level node

In python mode, the 2nd level can't be closed alone. If I want to close the 2nd level node, its parent node will be closed.

The add() can's be closed alone. If I want to close add(), the parent of add(), i.e, Sequential will be closed, as show in the 2nd attached file.
