Seems that the problem begins when xarray.core.nanops._nan_minmax_object converts the max index value (2,99) tuple (which is correct) to np.array((0,99), dtype='O') which is not because np.array converts this from dims=() to dims=(2,).

Which is now incorrect. Interesting... how do you tell numpy to create a 0 dimension array with a tuple?
