Maybe slicing uses the standard (excluding) python slice() for these dimensions and continues to use the (including) pandas slice for coordinates?

Yes, this is what xarray does since 0.9. From the indexing section of the documentation:

Label based indexing with .sel and .loc uses standard positional, integer-based indexing as a fallback for dimensions without a coordinate label.

To fix your scripts you have to choose between set range coordinates or update the slice values.
