it seems the calls to array-copy here are calling a private function. should I post an issue about this? https://github.com/clojure/core.rrb-vector/blob/master/src/main/cljs/clojure/core/rrb_vector/nodes.cljs#L94

they are not reported because of some other JIRA issue: unqualified calls to private functions to cljs.core are not reported

@borkdude I guess we could make that public - it doesn't seem like a big deal to me
