What is your issue?

When doing arithmetic operations on two Dataset operands, the keep_attrs=True option is ignored and therefore attributes not kept.

Minimal example:

```python import xarray as xr

ds1 = xr.Dataset( data_vars={"a": 1, "b": 1}, attrs={'my_attr': 'value'} ) ds2 = ds1.copy(deep=True)

with xr.set_options(keep_attrs=True): print(ds1 + ds2) `` This is not true for DataArrays/Variables which do takekeep_attrs` into account.

Proposed fix/improvement

Datasets to behave the same as DataArray/Variables, and keep attributes during binary operations when keep_attrs=True option is set.
