When you use a kepub, you trigger Kobo's advanced renderer.
When you use an epub, you trigger Kobo's old renderer which I believe is
ADE.
The two renderers do things differently which is why the different files
appear to have different results. However the kepub is almost the same
as the epub, it just has extra <span>s which the kepub format requires.

Du Bois to encourage using the capitalized spelling. That's as far as our SE editorial policy goes.
