This does look like a bug, here's another case:

```python In [78]: ...: >>> a = np.arange(0, 5, 1) ...: >>> b = np.linspace(0, 1, 5) ...: >>> ds = xr.Dataset({"a": ("x", a), "b": ("x", b)}) ...: >>> ds Out[78]: <xarray.Dataset> Dimensions: (x: 5) Dimensions without coordinates: x Data variables: a (x) int64 0 1 2 3 4 b (x) float64 0.0 0.25 0.5 0.75 1.0

In [79]: ds.query(x="a > 2") Out[79]: <xarray.Dataset> Dimensions: (x: 2) Dimensions without coordinates: x Data variables: a (x) int64 3 4 b (x) float64 0.75 1.0

In [80]: ds.set_coords('a').query(x="a > 2") Out[80]: <xarray.Dataset> Dimensions: (x: 2) Coordinates: a (x) int64 3 4 Dimensions without coordinates: x Data variables: b (x) float64 0.75 1.0

In [81]: ds.set_coords(['a','b']).query(x="a > 2")

fails

```
