"Invalid self argument" for numpy's `iadd`

To Reproduce

from typing import Any

import numpy as np
import numpy.typing as npt

def plus1(array: npt.NDArray[np.integer[Any]]) -> None:
    array += 1

Expected Behavior

No error

Actual Behavior

error: Invalid self argument "ndarray[tuple[int, ...], dtype[integer[Any]]]" to attribute function "iadd" with type "Callable[[ndarray[tuple[int, ...], dtype[numpy.bool[builtins.bool]]], _SupportsArray[dtype[numpy.bool[builtins.bool]]] | _NestedSequence[_SupportsArray[dtype[numpy.bool[builtins.bool]]]] | builtins.bool | _NestedSequence[builtins.bool]], ndarray[_ShapeT_co, _DType_co]]" [misc]

Your Environment

• Mypy version used: 1.16.0
• Mypy command-line flags: none
• Mypy configuration options from mypy.ini (and other config files): none
• Python version used: 3.13.2
• Numpy version used: 2.2.6

Start by running the provided Python snippet with mypy 1.16.0 and NumPy 2.2.6 to reproduce the invalid self-argument error. Trace the typing of NDArray's iadd handling and compare it with the expected integer-array behavior. Done means the example type-checks without the reported error and related checks still pass.
