pyright error Argument missing for parameter "self" when plot

[singledoggy]

I have been using xarray for several years and recently began using Pyright. However, I encountered the following error: Argument missing for parameter 'self' Although my code still executes normally, I am curious about the cause of this error. Is this behavior expected?

import xarray as xr
import matplotlib.pyplot as plt
data = xr.DataArray([1, 2, 3], dims=['x'])
fig, ax= plt.subplots(ncols=1, nrows=1)
data.plot(ax=ax)

It seems to related to the codes here:

    plot = utils.UncachedAccessor(DataArrayPlotAccessor)

class UncachedAccessor(Generic[_Accessor]):
    """Acts like a property, but on both classes and class instances

    This class is necessary because some tools (e.g. pydoc and sphinx)
    inspect classes for which property returns itself and not the
    accessor.
    """

    def __init__(self, accessor: type[_Accessor]) -> None:
        self._accessor = accessor

    @overload
    def __get__(self, obj: None, cls) -> type[_Accessor]: ...

    @overload
    def __get__(self, obj: object, cls) -> _Accessor: ...

    def __get__(self, obj: None | object, cls) -> type[_Accessor] | _Accessor:
        if obj is None:
            return self._accessor

        return self._accessor(obj)  # type: ignore  # assume it is a valid accessor!

Here is my xarray version:
