Uglify errors with jarallax

[zimonline]

I am getting the following error when I try to uglify the following.
I don't think the problem is with jarallax as code works fine on its own.

Contents of app.js

import {
    jarallax,
    jarallaxElement,
    jarallaxVideo
} from 'jarallax';

Error

@evilebottnawi This bug has nothing to do with inline and is not addressed by #264.

It is resolved by replacing uglify-es with terser in #296.
