Fails to load required google closure's namespace in the loaded module.
The codes here are taken from the guide https://clojurescript.org/guides/code-splitting and modified to reproduce the bugs.
basically, I modified the src/bar/core.cljs from above guide like this:
(ns bar.core
(:require
[goog.net.cookies :as gcookies] ;; I require goog.net.cookies
[cljs.loader :as loader]))
(enable-console-print!)
(defn cookie-enabled? ;; I create wrapper function
[]
(.isEnabled goog.net.cookies))
(println "I'm bar!")
(defn woz []
(println "WOZ!")
(println "cookie enabled?" (cookie-enabled?))) ;; call cookie-enabled?
(loader/set-loaded! :bar)The result in chrome's console when I click the Load Bar! button in the browser are:
Uncaught TypeError: Cannot read property 'isEnabled' of undefined

at cljs$loader$set_loaded_BANG_ (loader.cljs:80)
but if I click the Load Bar! button again, everything works and the chrome's console prints:
WOZ!
