Description

Create a 4MB, non-sparse parent image and clone it to a new 4MB child image. Take a snapshot, shrink the image down to 1MB and resize it back to 4MB, and take a second snapshot. The diff report should show that image extents 0MB-4MB are dirty (preferably that 1MB-4MB are zeroed) but instead it shows that only 0MB-1MB is dirty.
