The frame problem might appear overrated if you imagine that DOM nodes need to be "passed" between frames. But accessing an iframe's DOM nodes is trivial property lookup, theFrame.contentWindow.querySelector(...). That simplicity plus the experience of no significant issues in operating on the iframe content encourages this usage pattern. Mostly devs avoid instanceof, but eventually you end up using instanceof on an array. Nothing noticeable happens when you do, other than your app is broken. Once you track it down you are totally convinced that the browser is busted because the instanceof test fails. You waste a day writing a test case to prove it. So this iframe problem is rare but hits very hard: you already have a big investment in some code and you have to work hard to figure out what went wrong. jjb
