1115166039 I_kwDOAMm_X85CeBVX 6196 Wrong list of coordinate when a singleton coordinate exists 32069530 open 0     5 2022-01-26T15:41:37Z 2023-03-01T19:55:13Z   NONE      

What happened?

Here is some simple code: a = xr.DataArray(np.arange(5), dims='x', coords={'x':np.arange(5)}) a = a.assign_coords({'y':1}) Now calling a['x'] or a['x'].coords shows y as a coordinate of x, which is unexpected for me

What did you expect to happen?

I expect that a singleton coordinate of a dataset not to be a coordinate of other coordinates present in the dataset

Minimal Complete Verifiable Example

import xarray as xr import numpy as np a = xr.DataArray(np.arange(5), dims='x', coords={'x':np.arange(5)}) a = a.assign_coords({'y':1}) print(a['x'].coords) returns Coordinates: * x (x) int64 0 1 2 3 4 y int64 1
