We also need to check whether the components will change by verifying whether components will change by looking into the matched property. (If they don't, then page:finish won't be called and the transition will abort.)

Alternatively, we can update view-transitions implementation so finishTransition is called after the route updates, even if there has been no call of page:finish.
