* 1. The matched route is undefined. This means that
* the matched route is not applicable to this outlet.
* For example, a /settings route is not applicable
* to a /tabs/... route.
*
* Note: When going back to a tabs outlet from a non-tabs outlet,
* the tabs outlet should NOT attempt a page transition from the
* previous tab to the active tab. To do this we compare the current
* route with the previous route. Unfortunately, we cannot rely on the
* previous value provided by Vue in the watch callback. This is because
* when coming back to the tabs context, the previous matched route will
* be undefined (because nothing in the tabs context matches /settings)
* but the current matched route will be defined and so a transition
* will always occur.
*
* 2. The matched route is defined and is different than
* the previously matched route. This is the most
* common case such as when you go from /page1 to /page2.
*
* 3. The matched route is the same but the parameters are different.
* This is a special case for parameterized routes (i.e. /page/:id).
* When going from /page/1 to /page/2, the matched route object will
* be the same, but we still need to perform a page transition. To do this
* we check if the parameters are different (i.e. 1 vs 2). To avoid enumerating
* all of the keys in the params object, we check the url path to
* see if they are different after ensuring we are in a parameterized route.
