Summary Promise rejections in top-level await can't be handled

When a Promise is rejected in a JavaScript module in a top-level await position, there is no way to handle the error in WebKit. Given an HTML document <html> <script src="test.js" type="module"></script> </html> and a script // test.js window.onerror = console.log; window.addEventListener('unhandledrejection', console.log) await Promise.reject(new Error('This should be handled')); export {}; WebKit doesn't propagate the rejected Promise to the error handlers on window and instead crashes silently. Both Gecko and Chromium let us handle this kind of error with `window.onerror`.
