Glossary term swapping not working as expected

[leximation]

If a glossary map has navtitles on glossrefs, and those navtitle values are the full text of the glossary title, all instances of a reference to the glossary term will be the full glossary title not the abbreviation. If "Glossary Term Swapping" is enabled in the Book Build Options, you'll expect that second and later instances of the glossary term reference will be swapped. If the glossref entries are created without navtitles, the feature works as expected. Need to decide if this is a proper implementation.
Noticed on FM2019 with FMx 2.0.07, but not FM or FMx version-specific.

I have a minor reaction that you should ignore on . In DITA 1.3 spec, does not specify a behavior if is present. And “Specifies the title of the topic as it will appear in the navigation or tables of contents that are generated from the map.” So this behavior deviates from the spec, IMO. But I don't feel strongly about it. It's easy to avoid (don't use navtitle on glossref), and could be a desired behavior.
