Unexpected behavior at the end of docstring

[kkew3]

How to reproduce

_ denotes the cursor location.

def f(a):
    """_

Now type <Enter>. It becomes:

def f(a):
    """[summary]
    
    [description]
    :param a: [description]
    :type a: [type]
    """

Now [summary] is selected. Typing <Tab> four times, the cursor should jump to:

def f(a):
    """[summary]
    
    [description]
    :param a: [description]
    :type a: [type]
    """_

To continue writing, one would type <Enter>. However, it renders:

def f(a):
    """[summary]
    
    [description]
    :param a: [description]
    :type a: [type]
    """[summary]
    
    [description]
    :param a: [description]
    :type a: [type]
    """

with the second [summary] selected.

Expected behavior

The last <Enter> in the previous example should trigger only an "Enter" rather than insert another block of docstring.

Current workaround

Type Ctrl-<Enter> instead. However, this seems awkward as it breaks normal workflow.
