An creates a completely separate browsing context with its own window object, its own document, and most importantly;its own prototype chain. A function hooked on HTMLMediaElement.prototype in the parent window is not the same object as HTMLMediaElement.prototype in the iframe’s window. They’re entirely separate objects. If fermaw’s audio element lived inside an iframe, my prototype hook in the parent window would never fire.
