With ClojureScript 1.10.238, if you call {{.apply}} with over 21 arguments on a function that has been instrumented with {{cljs.spec.test.alpha/instrument}}, you will get an error about invalid arity. This problem does not occur with ClojureScript 1.9.954.
`
(require '[cljs.spec.alpha :as s] '[cljs.spec.test.alpha :as stest])
(defn my-fun [& args] (prn :args args))
(s/fdef my-fun :args (s/cat :args (s/* any?)))
(.apply my-fun nil (into-array (range 22)))
;; :args (0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21)
(stest/instrument)
(.apply my-fun nil (into-array (range 22)))

`
Regular {{apply}} works as expected.
