Overview

PromiseRejectionEvent — fired as unhandledrejection / rejectionhandled when a promise rejects with no handler (event.promise / event.reason). Critically, its mere existence is what Promise feature-detection (core-js et al.) checks: without it, libraries decide the native Promise is incomplete and swap in a polyfill whose microtask queue the host scheduler cannot flush — silently starving every .then/await and hanging SPA hydration (this is why note.com rendered only a shell).
