Expected behaviour

Intellisense should show descriptions of function/method parameters of the Docstring as you type then, like the example below.

Actual behaviour

When the descriptions of function/method parameters takes more than one line in the docstring, the descriptions shows only the first line.

Steps to reproduce:

Write a function like the one show above with multiline parameters descriptions in the docstring, and try to use it, or try to use a function that already exists.

Here is the snippet, to help:

def foo(a:int,b:float,c:str):
    """
        Parameters
        ----------
            a (int): integer number.
            b (float): description that takes
                more than 1 line in docstr
            c (str): word.
    """
    pass
