ui-router: [ng2] Uncaught (in promise): TransitionRejection(type: 5, message: The transition was ignored., detail: "undefined")

A bug easy to reproduce with the ng2 ui router, just start the quickstart example (https://github.com/ui-router/quickstart-ng2), click on one of the state links (Foo for example), then reclick on Foo.

You get the following error in the console:
