Issue: when spot moves out of any container, the nearest
neighbor
algorithm finds the neighbor based on the container bounds.
That is causing the issue.
Fix:  getNearestNeighbor method is updated to
consider the 'container' scenario and changed the bounds to container to
container's focused child.
