crossOriginIsolated was the test for "the popup can't message us back", but being isolated also requires COEP. A site sending COOP: same-origin on its own still has its opener relationship severed when it opens the Puter popup, and took the watch-the-window path instead — where the detached proxy reports closed === true on the first tick, so requestPermission resolved false about a second after the popup opened, while the user was still reading the dialog. Their "Allow" then had nowhere to go. Treat an already-closed popup as severed and poll. Pin the expected event.source before those early returns. popupWindow was assigned after them, so for the whole consent-dialog wait — as long as the user takes to click Continue — the handler accepted a decision from any window on the GUI origin. A forged answer is only advisory since the grant is written server-side, but the check may as well hold. Settle instead of rejecting when the consent dialog can't be appended: document.body is null in a <head> script, and the throw both rejected a promise documented to resolve to a boolean and left the message listener behind.
