When reading a sub group from a netCDF file with dimensions defined in the root group, the dimensions are not read from the root group. This contradicts the netCDF documentation, which states that dimensions are scoped such that they can be seen by all sub groups.

To be clear, xarray does properly read "dimensions" in parent groups. (This is actually ensured by libraries like netCDF4-Python.)

What xarray doesn't do is read "coordinates" from parent groups. As far as I can tell, this isn't part of either the netCDF4 data model or CF conventions. This might be a usability improvement but the right way to do isn't dictated by the specs.
