> This failure is due to the test assuming that more than one scan is necessary to scan the entire map, but for small map sizes (the map in the failure above only has 2 keys) it's possible that the first scan will return all elements and a cursor value of 0, meaning that the second scan will also return all elements, leading to duplicate elements in the result.
