Apparently it's possible to work around this by using merge() instead of assigning. 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"]) ```
