PyCharm console and decorators

I have a module that looks like this:

import functools


def decorator(f):
    @functools.wraps(f)
    def wrapper(*args, **kwargs):
        print('hello world')
        result = f(*args, **kwargs)
        return result
    return wrapper


@decorator
def add(a, b):
    print(a + b)

In the editor, if I then type `add(` and hit CTRL+P, I see "a,b" as the parameter hints, as I would expect. 

However, in the PyCharm console, I see "(*args, **kwargs)" as the parameter hints, which is not helpful or desired. Is this a bug in the PyCharm console?
