How to capture errors outside Angular context in zoneless? #56240

Which @angular/* package(s) are the source of the bug?

core

Is this a regression?

No

Description

When working with zone.js we can easily capture errors (inside and outside Angular context) in the ErrorHandler using a CustomErrorHandler. When going zoneless we can no longer get both kinds of thrown errors.

Please provide a link to a minimal reproduction of the bug

https://stackblitz.com/edit/stackblitz-starters-ggzajl?file=src%2Fmain.ts

Please provide the exception or error you saw

When we have zoneless we can listen only to errors thrown in Angular context. 
When we have zone enabled we can listen to all errors.

Please provide the environment you discovered this bug in (run ng version)

No response

Anything else?

This is probably correct behavior, but is there any way to get these errors through the custom error handler?
