### Ionic Framework Version
v7.x
### Current Behavior
If I try to use the [Lifecycles](https://ionicframework.com/docs/react/lifecycle) on Nav components it does not work.
Navigating between Components inside a IonNav does not fire the lifecycle hooks.
This is frustrating because I want to handle the BackButton event on specifict components but i can't if i don't have this hooks
If i handle it in a useEffect then if i have 4 nav components mounted it will trigger the backButton in all of 4, and I only want to trigger on the current view.
### Expected Behavior
To have the Lifecycles working on the nav components
### Steps to Reproduce
1) Start in a page with ``
2) Push another page that have `IonViewWillEnter` and `IonViewWillLeave`
3) Then go back
You will see that neither of those hooks will trigger

Hướng nghiên cứu
Start by running the reproduction at https://github.com/FernetB/ionic-tabs-bug and compare IonNav behavior with the React lifecycle documentation linked in the issue. Trace how IonNav navigation handles IonViewWillEnter and IonViewWillLeave; done means those hooks fire when views are pushed and popped, without triggering for inactive mounted views.
