Loading the polyfill intersection observer does not check the right key

Thanks @yareckon, nice catch!
Merging MR !17 ... going to deploy a new 3.0.18 release with this fix/update.

@itamair Thanks for your quick fixes but I see in the commit 1bdbd542 → from above a link reported as malicious was inserted. Please check polyfill-service page. You will see a big banner saying

This repository contains malicious content that may cause technical harms.

. Probably this patch #11 from → issue 3456704 📌 polyfill.io Library is no longer considered safe to use Fixed is safer.

thanks @CPatrone ... but don't worry, I made sure that
this embedded (and frozen) /js/polyfill/polifillIntersectionObserver.min.js file is the minified matching the one provided with Fastly.io: https://polyfill-fastly.io/v3/polyfill.min.js?features=IntersectionObserver

If you are able to test with IE 11 you also will evidence of that.
