flashy is not defined

[mdeherder]

Hello,
If I activate the option :

script_attributes:
        defer: true

in webpack_encore.yaml,

i get the following error when the page loads and a flash message should be displayed:

Uncaught ReferenceError: flashy is not defined

If I remove the 'defer' option the flashy message is correctly displayed.

Symfony 5.3.0-BETA4 and mercuryseries/flashy-bundle 4.0.0

When including the library in your app.js file, you have to make globale flashy, like this :

import flashy from "./flashy";
window.flashy = flashy;
