IIRC an iframe contents is treated as a separate window, so cookies aren’t shared either

That’s horrific WHY?

do not add any event listeners for message events. This is a completely foolproof way to avoid security problems. 🤡🤡🤡🤡🤡🤡🤡🤡🤡🤡🤡

Sure, but the separate window can be on a different domain. Now you have a way to share cookies across multiple websites on different domains if all of them include an iframe to this external domain. And you can use in-browser messages (see window.postMessage()) to communicate between iframes and main window.
