Thanks ps67, upon your suggestion I installed the KFX Output plugin (and the Kindle Previewer as its prerequisite) and tried to convert the epub to KFX but received the following error:

ERROR: KFX conversion failed: Cannot convert The Book
Conversion error:Kindle Previewer error: Error:E00837: "Unsupported mathml tag found."


So, it seems MathML is involved as you suggested. However, the Calibre viewer displays the AZW3 conversion just fine on the desktop.
