Wrong "Incorrect arity" on top-level function calls inside deftest: claims the arity is 1 larger than it actually is

[luontola]

In the following code, the top-level function calls inside foo2 have false warnings about incorrect arity, but the identical calls inside foo1 are fine. Invalidating caches doesn't help.

(ns example
  (:require [clojure.test :refer :all]))

(defn foo1 []
  (is (= 3 (+ 1 2))
      "math")
  (cons nil 1)
  (count []))

(deftest foo2
  (is (= 3 (+ 1 2)) ; Incorrect arity 3 for clojure.test/is
      "math")
  (cons nil 1) ; Incorrect arity 3 for clojure.core/cons
  (count [])) ; Incorrect arity 2 for clojure.core/count

I just tried to reproduce this with latest Cursive, and I can't - is this still happening for you?

[luontola]

It's still happening with Cursive 1.12.4. It was still happening directly in my primary work project, after which I tried reproducing it in a minimal blank project: at first the bug didn't appear, but after Invalidate Caches and restarting IDEA the bug appeared also in that minimal project:
