A good reason why using the correct syntax and keeping an eye on file sizes is important.
And this is just on a Kobo ereader. Similar issues exist on every ereader I've tried.

I read all the epub2 spec and all the result of "
epub footnotes site:mobileread.com", follow the rules in some demo epub file in the links which is popup note on my Kobo, shrink the long footnote content and move the position of the footnote close to the reference node, pass the epubcheck check, they are still not popup.
BUT I managed to make the notes popup in other 2 books (I only tried 3 files including the Ulysses file, but it is chaos, I keep it untouched).
The solution is:
split the html files
- add "
page-break-before: always;" in stylesheet, for header tag or for just the footnote content part which lists all the footnote content.
- convert the epub file, the html will be split into multiple html files
- send the converted file to kobo
but the html files are not big, one is 60kb and the other is 100kb, don't know why it is a problem for kobo. Anyway, maybe it doesn't work for all cases, I'll use this method in the future and see how it goes.
And thanks for the help, learnt a lot.
