The following produces the expected output:
```
import numpy as np
import xarray as xr

ds = xr.Dataset()
ds[""a""] = xr.DataArray(np.linspace(0., 1.), dims=""x"")

ds[""x""] = xr.DataArray(np.linspace(0., 2., len(ds[""x""])), dims=""x"")
ds[""x""].attrs[""foo""] = ""bar""

print(ds[""x""])

#ds[""b""] = xr.DataArray(np.linspace(0., 1.), dims=""x"")
ds = ds.merge(xr.DataArray(np.linspace(0., 1.), dims=""x"", name=""b""))

print(ds[""x""])
