Key is revealed in debug console

[Palciny]

Hi, I have created encoded message https://mzl.la/2yFqixl and looked to the developer console.
I was surprised when I saw there key I have encrypted message with.
storage is: Object { message: "🍭🙆🌴🚂 💫🌴💫🌴 🚂📣 💫📣🍒💫🌴🌝🏉🐂💻🏉 🍒❤💺🏉🌝🏉🗾 🐠💫🌴💺🏉 ⛪😄👩📣 🎉🏉🐠🌴👩🌴🌝🏉🚓🏉🙍", key: "🍺" }

Than I have analyzed network activity and find out that
https://codemoji.org/app.js?v=880.3432085551322

return function:

function r() {
        var e = d(), t = e.queryGet();
        !_.isEmpty(t) && t.data && (p = f(t.data), e.querySet({}), c(e.toString()), console.debug("storage is:", p))
    }

Problem is that console.debug("storage is:", p) is called in production.
