For URLs that use auxiliary route outlets in the second or following path segments, when removing the auxiliary route segment, parenthesis remain for the primary outlet segment. This causes the following error when trying to reload an URL: "Cannot match any route". The commit adds a check for this scenario, serializing the URL as "a/b" instead of "a/(b)".

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.
