```python
In [1]: import xarray as xr
 
In [2]: import numpy as np

In [3]: ds = xr.Dataset({""1"": xr.DataArray(np.zeros(3), dims=[""a""], coords={""a"": list(""xyz"")})})

In [4]: ds
Out[4]: 
<xarray.Dataset>
Dimensions:  (a: 3)
Coordinates:
  * a        (a) <U1 'x' 'y' 'z'
Data variables:
    1        (a) float64 0.0 0.0 0.0

In [5]: ds[""2""] = xr.DataArray(np.zeros(2), dims=[""a""], coords={""a"": list(""xy"")})

In [6]: ds
Out[6]: 
<xarray.Dataset>
Dimensions:  (a: 3)
Coordinates:
  * a        (a) <U1 'x' 'y' 'z'
Data variables:
    1        (a) float64 0.0 0.0 0.0
    2        (a) float64 0.0 0.0 nan

```

I tested this with

```python
xarray: 0.17.0
pandas: 1.2.3
numpy: 1.20.1
```

Should we close this?
