46482d30caFor the path to be accurate it needs to be calculated at the moment of op insert not at commit. This is because the path may contain list indexes in parent objects that could change by inserts and deletes later in the transaction. The primary change was adding op_observer to the transaction object and removing it from commit options. The beginnings of a wasm level `applyPatch` system is laid out here.
