Research direction
Start with the cross-window communication page at javascript.info/cross-window-communication and review its CORS discussion. Add the file: protocol exception and the linked MDN reference, explaining the relevant cross-window messaging workaround; done when the page accurately covers this case.
Written by the indexing model from the issue text.
Description
In your page, https://javascript.info/cross-window-communication, an important CORS exception, to me at least, is that the protocol "file:" is always considered to be cross-domain. If you are writing javascript that has to work from a "file:" url, it can't access other local files directly (https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS/Errors/CORSRequestNotHttp). You have to use cross-window messaging to talk into/out-of an iframe.
