Yes, even with the option `xr.set_options(keep_attrs=True)`, I still encounter the attributes changed. The full code with the set options is below.

<details>

#### Inputs

```python
import xarray as xr
import numpy as np

xr.set_options(keep_attrs=True)

import xarray as xr
import numpy as np

var1 = np.linspace(10, 15, 100)
var2 = np.linspace(5, 10, 100)
coords = np.linspace(1, 10, 100)

dat = xr.Dataset(
    data_vars={'var1': ('coord', var1), 'var2': ('coord', var2)}, 
    coords={'coord': coords}
)
dat.attrs['model_id'] = 'model1'

# coarsen dataset
dat = dat.coarsen(coord=5, keep_attrs=True).mean()

# print dataset
dat
```

#### Actual Output

```python
<xarray.Dataset>
Dimensions:  (coord: 20)
Coordinates:
  * coord    (coord) float64 1.182 1.636 2.091 2.545 ... 8.455 8.909 9.364 9.818
Data variables:
    var1     (coord) float64 10.1 10.35 10.61 10.86 ... 14.14 14.39 14.65 14.9
    var2     (coord) float64 5.101 5.354 5.606 5.859 ... 9.141 9.394 9.646 9.899
```

#### Expected Output

```python
<xarray.Dataset>
Dimensions:  (coord: 20)
Coordinates:
  * coord    (coord) float64 1.182 1.636 2.091 2.545 ... 8.455 8.909 9.364 9.818
Data variables:
    var1     (coord) float64 10.1 10.35 10.61 10.86 ... 14.14 14.39 14.65 14.9
    var2     (coord) float64 5.101 5.354 5.606 5.859 ... 9.141 9.394 9.646 9.899
Attributes:
    model_id:  model1

I'm not too familiar with the xarray package internals. But I will look to see if I can do my part and do a pull request. I'll get back to you after having a look at the internals.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,503425825
