The NodeIdentifier struct essentially contains the DOM node ID within its WebContent process. These will repeat across multiple processes, thus we cannot use them to search for node actors in the global actor registry. Instead, we can store a map of all node actors created by the walker itself. The NodeIdentifier is then appropriate for actor lookups on that map. This has the added benefit of not needing to search the entire actor registry many times while forming the DOM node caches. This fix allows us to inspect multiple tabs at once.
