In the ePub each chapter starts with the book title using <h6> followed by the chapter name using <h2>. On conversion to AZW3 these <h6> and <h2> tags become separated by a page break. How can I avoid this so that the <h6> and <h2> remain on the same page?

Exploding the AZW3 shows that the <h6> has actually been kept with the <h2> for Part0003.html, but after that these tags become separated.

Input, output and conversion logs files as attached. Default options used.
