Purpose: This case tests moving an animated sub-tree from one SVG document fragment to another. Different document fragments have different time containers and so this test ensures the animation is correctly transferred from one time container to the other.
Operation: Both animations contain a moving box. The first animation also contains a circle. After 1.5s, both this circle and its child animation element are removed from the first animation and added to the second animation.
Expected results: The circle moves right in the first box and then continues moving right in the second box from the same offset.
