Previously, if a book had no text content in a section, then no location would be generated. In the pathological case of a book with no text content at all (pictures only), no locations are generated for the entire book. An example of this is the Open Circuits EPUB from No Starch Press (2023). By moving the "empty node" detection after the creation of the initial opening range, the parsing code ensures that a minimum of one location is generated per section.
