Interesting tidbit about it being an ePub viewer.
Converted from Markdown TXT to ePub, and it looks good in Sigil.
Converted Markdown TXT to Mobi (results on Kindle as above) and then from that Mobi to ePub, and it again looks good in Sigil.
So it's not like the file is irreparably damaged, it just seems to quite predictably come out as a file that Kindle Previewer and the actual Kindle don't fully like.
