Why is my react-lazyload component not working? - reactjs

Question

Up until a few days ago, my implementation of LazyLoad was working perfectly, but now I can't seem to get it to work.
This is my component:
import React from 'react';
import LazyLoad from 'react-lazyload';
import './image.scss';
const Image = image => (
<LazyLoad height={200} offset={100} once>
<div
className="image-container"
orientation={image.orientation}>
<img
className="image"
src={image.url}
alt={image.alt}
/>
{'caption' in image &&
<div className="meta">
<p className="caption">{image.caption}</p>
<p className="order">{image.currentNumber}/{image.maxNumber}</p>
</div>
}
</div>
</LazyLoad>
)
export default Image
And in App.js it is called like this:
render() {
return (
<div className="wrapper">
<GalleryTop details={this.state.gallery_top} />
{this.state.images.map((image, index) => <Image key={index} {...image} /> )}
</div>
)
}
But it won't work! Here's the demo environment:

(Check Network tab in Inspector to see that images are all requested from initial load)
There's also a video here
Any idea about what I am doing wrong?
Thanks in advance,

I ran into similar issues with the npm package react-lazyload. For one, this package only allows one child per LazyLoad component, so you would have to rearrange your hierarchy to make it work. Secondly, I found some strange behaviors when loading images that were already set within the viewport. The documentation does list import {forceCheck} from 'react-lazyload'; combined with forceCheck(); as a means of manually checking the elements, but I found this inconvenient and insufficient for components that aren't rerendering.
I was able to obtain the exact same functionalities with an easier implementation from the alternative package react-lazy-load. Mind the hyphen. This package also requires node>0.14. More or less, it does the same thing. You can read their documentation here: react-lazy-load
