Hmmm ... now I feel like a real dummy.
Well, thanks to both of you for this. I started this book about 10 years ago and have been working on it sporadically since then. Originally I was testing my Sigil version by converting to a Kindle format with Calibre. But since then I've just been working in Sigil and not converting to Kindle to test for several years now. So what you're saying is enlightening and of course now my whole understanding of the Kindle publication process has changed as well (since the Kindle publication process has changed). I've just downloaded the Kindle Previewer for the first time, and this seems to really simplify things. Testing should be easier.
Duh.
One remaining question: Given that this popup footnote/endnote behavior is app-specific, is it documented anywhere? I haven't managed to come across it anywhere and so have gone off in the direction of implementing the behavior in Epub3 -- which is clearly a waste of time if the target is Kindle. Does Amazon document features like this somewhere? The KDP "Create Links to Footnotes" page doesn't mention anything about this, and the HTML code example there does not exhibit the necessary pattern.
