False 'no-member' on inner class of NamedTuple

[Lambda-Logan]

The following produces a 'no-member' error.

from typing import NamedTuple


class Ax(NamedTuple):
    class Bx:
        b = 0


print(Ax.Bx.b)

>>> pylint_no_member.py:9:6: E1101: Class 'Ax' has no 'Bx' member (no-member)

However, if Ax doesn't inherent from NamedTuple then it's fine.

Thank you for the report, I can reproduce this.
