As you are well aware, the physics behind acoustics and electromagnetics are very similar. The term overtone definitely has an acoustic pedigree, whereas the term harmonic has been adopted by electrical engineering. But the 1st overtone explicitly contains the info that we are talking about a component at a higher frequency than the fundamental. The term harmonic simply means that the various components are related to each other by ratios of whole numbers, including the number one. The fundamental is the first harmonic. The second harmonic is the first overtone. This seems eminently sensible, intuitively appealing, and as I said previously, these are accepted definitions going back decades in my experience, but likely hundreds of years. Should not be a topic involving lengthy debate.
