Code Sample

Problem description

The current behaviour of xarray.Dataset.sel when selecting time is that it returns a 3D array with the time dimension has a length of 0.

Expected Output

I expect that no time dimension is returned. This behaviour is as expected in xarray.Dataset.isel (look at the Jupyter Notebook screenshot above).
