### Prerequisites

### 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

调研方向

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.
