Expected

1. If the promise is rejected, the final callback should be executed
2. After that, it should throw the UnhandledPromiseRejection error

Actual without zone.js

Work as expected

Actual with zone.js

UnhandledPromiseRejection error is thrown only without finally callback

Side effect

Unhandled errors in promises with finally callback is missing. Console is empty. Logging systems also do not see such errors.
