Instead of traversing the DOM manually we should use Node.prototype.contains.

Utilities.js:
Object.defineProperty(Node.prototype, "isAncestor", ...
Object.defineProperty(Node.prototype, "isDescendant", ...
Object.defineProperty(Node.prototype, "isSelfOrAncestor", ...
Object.defineProperty(Node.prototype, "isSelfOrDescendant", ...
