Which @angular/* package(s) are the source of the bug?
zone.js
Is this a regression?
No
Description
The PromiseRejectionEvent is not triggered when zone.js is included on the webpage. The issue stems from zone.js's inability to construct a PromiseRejectionEvent because options parameter is undefined - { promise: undefined, reason: undefined }
Event is not fired and silently ignored here: https://github.com/angular/angular/blob/main/packages/zone.js/lib/common/promise.ts#L82
Fails to construct PromiseRejection error here: https://github.com/angular/angular/blob/main/packages/zone.js/lib/browser/browser.ts#L316
Here is a minimal example to reproduce the issue. Note that if you remove the zone.js script, the event fires as expected.
