Why is the polyfill wrapped to window.top instead of the actual window?
redfellow opened this issue · comments
I'm asking because window.top in a scenario where the Polyfill is running in an iframe, that has it's top window located in another domain triggers a CORS error. If I modify it to bind to the current window, things work as expected.
Hi, it was meant to be since the original development of the polyfill was
part of a communication mechanism between a iframe content and its parent
(and some other parts..). But your comment is correct and I'll change it
asap. Thanks!

Makes sense, and perhaps that functionality is important for some, but not others. Could be added in the readme :)
