I don't follow why we need to run these outside the zone. Sure they might trigger change detection, but at this point the app is likely in a broken state anyway.

I don't follow the comment. The error event is triggered by asynchronous errors thrown outside of the Angular zone; i.e., __zone_symbol__setTimeout(() => { throw new Error(...) }), which can occur in third-party libraries or external APIs. This does not necessarily mean the app is in a broken state.
The purpose of the error handler is to redirect the error to Angular’s ErrorHandler; it has nothing to do with triggering view updates.

This matches the behavior of the onError subscription where errors are sent to the ErrorHandler from outside the zone. I think it’s reasonable to at least keep consistent with that.

I guess I just don't see the point of running these outside the zone. It looks like these errors happen only once an error makes its way all the way up to the global handler which would be fairly rare. Will leave it up to @atscott since he has more context around error handling.

I agree that I think it's hardly worth doing to prevent running change detection. The only reason I feel it could be worth the change would be for consistency with what we do elsewhere.

@arturovt This change introduced a cyclic import, Can you take a look and see if we can fix it. |
This commit wraps the `error` and `unhandledrejection` event listeners so they are installed outside of the Angular zone, because otherwise they trigger change detection whenever the event callbacks are invoked.
