Both importers capped every side at 10cm, which is the Layout panel's limit and no file's: a back cover pushing its last lines to the page foot with a 21cm top margin rendered 11cm high. fitMargins caps only what would leave the page no strip of text at all, and the zone distances follow the page's own height.
