A mixin to lock the scrolling of a component's parents for react

	// Based on https://codepen.io/somethingkindawierd/post/react-mixin-scroll-lock
	// How this works is that it will lock the scroll of the component parents
	// and allow the current element to scroll

	import ReactDOM from "react-dom";

	const ScrollLockMixin = {
	scrollLock: function (scrollElement) {
	let p;
	this.scrollElement = scrollElement \|\| ReactDOM.findDOMNode(this);
