#load_node_properties(node, properties, ids_of_interest = :all) ⇒ Object

If we’re being asked to load an entire tree, don’t bother loading all of the instances that go with each node. This is a performance optimisation, since there can be tens of thousands of instances. The only place that pulls down the entire tree is the indexer, and it doesn’t need instance/container information from the tree anyway.
