Is your feature request related to a problem?

When using sortby with ascending=False on a DataArray/Dataset without an explicit index, the data gets correctly reversed, but it is not possible to tell anymore which ordering the data has.

If an explicit index (like [0, 1, 2]) exists, it gets correctly reordered and allowes correct aligning.

Describe the solution you'd like

For consistency with aligning xarray should create a new index that indicates that the data has been reordered, i.e. [2, 1, 0].

Only downside: this will break code that relies on non-existent indexes.

Describe alternatives you've considered
