If the scrollable element flowed into a region is large enough to not fit the region and generate scrollbars, the region cannot be scrolled all the way down to see the entire flowed element. See test-case.

Test-case 2

Apparently this issue also happens when flowing a div with a not-specified height or a specified height which is greater than the height of its contents. In that situation, the region cannot be scrolled all the way down to see the bottom border of the flowed div.
