### Ionic Framework Version

v7.x

### Current Behavior

When using the `IonNav` and `IonNavLink` components in Vue for routing, going 'forward' creates a new element in the DOM, but going 'backward' does not remove that element. This results in multiple duplicate elements being created when navigating backwards then forwards again (with the current screen being shown in a higher z-index).

As a side effect, it seems than whenever vue state is updated inside the `IonNav` component, a new component is created entirely, rather than updating the state correctly.

### Expected Behavior

Would expect `IonNav` to work correctly in navigating forwards and backwards through `IonNavLinks` without duplicating elements in the DOM, and correctly updating vue state within the components.

### Steps to Reproduce

1. `git clone https://github.com/0x467/ionic-ion-nav-bug-vue`
2. `npm install`
3. `npm run dev`
4. Navigate between pages using the given buttons and see the dom renders duplicate components
