This allows identifying a particular object when using the HeapSnapshot API.
HeapSnapshot.computeDominatorTree() returns a tree of objects, but there is no way to identify a given JS object in it.
Getting the node id of a given JS object helps you browse this tree from a given object you know is being leaked. Or just check if it is leaked at all.
