Interesting... none except mmat's seems to render as intended in Sigil (or consequently in Calibre). likewise, the mobi/KF8 conversions don't render correctly. It seems you can either design the epub to display correctly in calibre (and its KF8 conversion to render correctly on Kindle), or you can design it to render correctly on ADE, but not both.

EDIT: Wrote bad code... got bad result. GIGO. ignore this post
