説明

### Prerequisites

- [X] I have read the [Contributing Guidelines](https://github.com/ionic-team/ionic-framework/blob/main/.github/CONTRIBUTING.md#creating-an-issue).
- [X] I agree to follow the [Code of Conduct](https://ionicframework.com/code-of-conduct).
- [X] I have searched for [existing issues](https://github.com/ionic-team/ionic-framework/issues) that already report this problem, without success.

### Ionic Framework Version

- [ ] v4.x
- [ ] v5.x
- [X] v6.x
- [ ] Nightly

### Current Behavior

I've come across with some strange behaviour, when you present a page using `ModalController`which wraps `ion-nav`.

### Parent Page

```typescript
public async openModal() {
const modal = await this.modalController.create({
component: ModalOutletPage,
componentProps: { component: AddCardPage },
});

await modal.present();
}
```

### Modal Outlet Page

```typescript
export class ModalOutletPage implements OnInit {
@Input() public component: HTMLElement;
@Input() public componentProps: unknown;
}
```

```html

```

in this test i console.log() `ionViewDidEnter()`, `ionViewDidLeave()`, `ngOnInit()`, `ngOnDestroy()` inside `add-card.page.ts`

### First time opening modal:
#### on open
1. ionViewDidEnter trigger
#### on close
1. ngOnInit trigger
2. ngOnDestroy trigger

### second time opening modal:
#### on open
1. ngOnInit trigger
2. ionViewDidEnter trigger twice
3. ionViewDidLeave trigger
4. ngOnDestroy trigger
#### on close
1. ngOnInit trigger
2. ngOnDestroy trigger

#### UPDATE
This is the behaviour, if i remove `changeDetection: ChangeDetectionStrategy.OnPush` inside `modal-outlet.page.ts`:

調査の方向性

Start with the linked reproduction project and inspect modal-outlet.page.ts, add-card.page.ts, ModalController, and the ion-nav usage. Reproduce the modal open and close sequences with and without ChangeDetectionStrategy.OnPush, then compare the observed lifecycle events with the expected behavior described in the issue.
