Uncaught HierarchyRequestError: Failed to execute appendChild on Node: Only one element on document allowed.

See original GitHub issue

I did not change the code and I started to have this error on my website. I have only noticed this today

The error is in this line: var t, n = document.appendChild(document.createElement("body")), o = n.appendChild(document.createElement("iframe")), r = o.contentWindow.document, c = Element.prototype = r.appendChild(r.createElement("*")), d = {}, m = function(e, t) {

This is happening in all major browsers / recent versions. The URL I’m fetching is https://cdn.polyfill.io/v2/polyfill.min.js?features=fetch,setImmediate,matchMedia&flags=always,gated&unknown=polyfill&callback=arceus_callback_1 If I fetch the same URL without .min I see its the 3.12 version on the headers. Will provide a test later.
