I side-loaded an AZW3 comic (downloaded 'for transfer via USB' back in the day) and it works fine (except no cover thumbnail appears). Note this has ctype=EBOK.

KCC now I think uses ctype=PDOC but in past used ctype=EBOK.

I do not know if that matters, but it would be interesting to know if it does.

In any case AZW3 is easily inspected so some other difference in HTML/CSS might shed some light.
