The basic issue here seems to be that print (preview) displays scrollable areas at their initial scroll position, not using the current scroll position on the page. E.g. load https://www.w3.org/TR/wai-aria-practices-1.1/examples/listbox/listbox-scrollable.html, and scroll down the list of elements, then bring up the print preview panel: the top of the list is displayed.
Both Chrome and Safari render the scrolled list at its current scroll position in their print preview. That's probably more in line with user expectations when printing something like this.
