MOBI to EPUB Loses metadata TOC
When I view a MOBI book in Kindle Previewer and Kindle devices, I see the book's NCX view and content TOC.
When I view the same book in Calibre, pressing Table of Contents displays what appears to be the content TOC, contradicting the Calibre's FAQ statement that the viewer displays the metadata TOC.
Furthermore, when Calibre converts the MOBI book to EPUB, Calibre seems to ignore the input file's metadata TOC and instead builds an NCX based on the input file's content TOC. This is confirmed when examine the EPUB's NCX in Sigil.
Is there a way to do the MOBI to EPUB conversion without losing the input file's metadata TOC (NCX view) exposed in both Kindle Previewer and Kindle devices?
