Why is the polyfill wrapped to window.top instead of the actual window?

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! Il giorno gio 3 giu 2021 alle ore 09:16 redfellow ***@***.***> ha scritto:

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