family: animation: rotate image, not node
Previously, the active node was animated, which resulted in the nodes
moving out of their positions, getting disconnected from their edges in
the process. The animation is replaced to be on the nodeImage, so that
only the image is moved via the animation, keeping the nodes connected
with the edges
