Myeah. I was aware that `WindowProxy.location` exists, but not that `WindowProxy.frames` exists. To me, that's the more surprising part - as `window.frames[0].location` should indeed be writable, but I feel like accessing `window.frames[0].frames` is more debatable - even knowing the number of iframes in a page might leak information in certain cases.
