Currently tree nodes receive IDs that are unique by tree. If a new tree is created, the IDs are reseted. This means that we have artificial object constancy when transitioning between completely different trees. This also means that links between tree leaves and tracks are broken when different trees are used in the visualization and the ids are used as the linking mechanism.
It would be better to have unique ids across trees to avoid this problem.
