The custom unhandledrejection event propagation is not reliable when native async function throw errors. The event is fired before we have a chance to detect that the error was indeed handled in a later tick.
User code should not rely on unhandledrejection anyway but have it as a debugging tool rather - to detect errors in the code where promises aren't caught properly. Users that use async functions will get the native unhandledrejection functionality anyway, but those who still use promise-based .then()/ .catch() might not get this warning anymore after this commit. However, I believe it's better to not warn when the warning is not correct anyway.
