I think this is a duplicate of #4483: xarray.core.variable.as_compatible_data doesn't have a special code path for DataArray and thus falls back to: https://github.com/pydata/xarray/blob/333e8dba55f0165ccadf18f2aaaee9257a4d716b/xarray/core/variable.py#L219 where DataArray.values will cast using numpy.asarray.

You should be able to work around that by using either xr.Dataset(dict(a=(('x', 'y'), ds.a.variable)) or xr.Dataset(dict(a=(('x', 'y'), ds.a.data))

4493 tries to fix this, but importing DataArray in as_compatible_data to avoid circular imports feels a bit unclean.
