Just out of curiosity, I compared FFF's HTML with it after letting Calibre "help" (pasting it into an HTML longtext column). Main difference I see it adds several more divs, deletes a bunch of 'unused' spans & classes (which FFF uses to identify specific bits of metadata), and splits up the lines all over the place.

I get pretty much the same result if I open the column in NV's HTML editor and then simply save it.
