I do notice something different with the mobi of chapter 3 with the oversized page and the one without when viewed on the voyage:

In the mobi without the oversize page (pages have margins autocropped):
The menu option has this:
* Animation On/Off
* Fit to Screen On/Off

I'm not sure what Fit to Screen On/Off does but it doesn't cancel out the margin-cropping feature. The animation option enables a scrolling animation when in zoomed-in panel view.

Panel view, when activated, zooms in to each corner as expected.

In mobi with the oversized page (pages do not have margins autocropped):
In the menu, there are no options for Animation or Fit to Screen. Why is this mobi treated differently?

On pages showing the whole image along with the margins, when double-tapping the page to go into panel view (a rectangle appears in lower-right), the view doesn't automatically zoom it and tapping the page only goes to the next page. But when you get to the oversized page, it does zoom in for only that page. Shouldn't KCC have made all pages the same physical size? So it weird that the viewer would treat that one page differently.

Calibre doesn't give me the option to save the image for that one particular oversized page (unlike most other pages) so I can't confirm if the image size is the same as the others.
