In this case, I call `ds.expand_dims('new_dim')` on some dataset (not DataArray), e.g.:
```
ds = xr.Dataset({'testvar': (['x'], np.zeros(3))})
ds1 = ds.expand_dims('y').copy()
ds1.testvar.data.flags

  C_CONTIGUOUS : True
  F_CONTIGUOUS : True
  OWNDATA : False
  WRITEABLE : False
  ALIGNED : True
  WRITEBACKIFCOPY : False
  UPDATEIFCOPY : False
```
The `.copy()` workaround is not helping in this case, I am not sure how to fix this?","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,432798510
