When `canceledNavigationResolution='computed'`, the `Router` needs to handle the cases where errors are thrown. Previously, the logic was not updated and would simply do a `replaceState` rather than determining where in the history we should move to restore the page/url from before the failed navigation.

Angular Router
Managing state transitions is one of the hardest parts of building applications. This is especially true on the web, where you also need to ensure that the state is reflected in the URL. In addition, we often want to split applications into multiple bundles and load them on demand. Doing this transparently isn’t trivial.
The Angular router is designed to solve these problems. Using the router, you can declaratively specify application state, manage state transitions while taking care of the URL, and load components on demand.
