I was using `expand_dims` to add a named dimension back onto a DataArray, when the dimension had been previously removed with the `sel` method. I realize this may not be the best way of doing things, but I wanted to point out that there is a loss of functionality here.

```python
import xarray as xr
da = xr.DataArray([0,1,2], dims=['dim1'], coords={'dim1':['a','b','c']})
print(da.dims) # returns ('dim1',)
da = da.sel({'dim1':'a'})
print(da.dims) # returns ()
da = da.expand_dims(da.coords) # fails in 0.12.1
print(da.dims) # returns ('dim1',) in 0.12.0
