I'd expect the output for the pd.NA operations above to match the output of the equivalent np.nan operations. Method works fine when using np.nan and also works as expected when the column is first converted to an Int64 dtype column. . This error can also be reproduced by doing just this. We probably need to make a "mask-aware" version of our algorithms like cut. NA to a boolean value.
