IntersectionObserver polyfill not working properly #5

Hi,

The component seems to work perfectly in Chrome! Safari & Firefox seem to be using an IntersectionObserver polyfill which gives an error. Sadly breaking the functionality entirely;

Safari V10.1 (12603.1.30.0.34) https://cl.ly/0H34331E2R3f

Firefox V53.0.3 (64-bits) https://cl.ly/3E2b0R0H3h0y

Thank you for reporting this.

'll assume that Firefox is on OS X also.

I'll check Github to see if there are reported issues with the polyfill on those browsers. I'll also turn off minification in the call to polyfill.io to see if I can debug that, though I'm not traveling with my mac today.

Found the problem! Since we are using this in a Magento installation we are forced to include prototype.js. Apparently this was conflicting with the polyfill. Updating to a newer version of prototype.js fixed the problem.
