Unexpected behavior using with-out-str with print-error-report

problem

When using the new error reporting function print-error-report with with-out-str I get back an empty string and the error report still writes to the original output. E.g.:

(with-out-str (print-error-report e))

Results in an empty string.

repro

(def result
  (try 
    (assoc :foo :bar)
    (catch ^:sci/error js/Error e
      (with-out-str (print-error-report e)))))

(prn result)

The above code prints an empty string.

expected behavior

The code in repro should print the actual error message stored in result.

Publishing as 1.2.160. The way to do this now is to capture the output of *print-err-fn*:

(require '[nbb.error :refer [print-error-report]]
         '[clojure.string :as str])

(def result
  (try
    (assoc :foo :bar)
    (catch ^:sci/error js/Error e
      (let [lines (atom [])]
        (binding [*print-err-fn* #(swap! lines conj %)]
          (print-error-report e))
        (str/join "\n" @lines)))))

(println "Error:")
(println result)

Awesome. Thanks a lot again.
