Optional arg is not seen, if we have mypy info (eg, `def fun(x: bool = True)`)

Hello, I've an issue with

def fun(x: bool = True):
    """This is my docstring.

    Args:
        x (bool, optional): some condition

    """
    if x:
        print("A")
    print("B")

which gives a.py:fun:5: DAR103: ~x: expected bool but was bool, optional.

Remark that

def fun(x=True):
    """This is my docstring.

    Args:
        x (optional): some condition

    """
    if x:
        print("A")
    print("B")

works fine, ie the problem seems to come from the : bool mypy hint.
