## What is the current behavior?
<!-- Please describe the current behavior that you are modifying. -->
Ionic lifecycle hooks do not execute a cleanup function when the
underlying `useEffect` is unmounted.
```ts
useEffect(() => {
return () => {
console.log('cleanup'); // called
};
});
useIonViewWillEnter(() => {
return () => {
console.log('cleanup'); // never called
};
});
```
Ionic's implementation registers the lifecycle callback to be handled at
a later time, by the page managers. However, it does not keep a
reference to the returned callback, so it cannot execute it when the
`useEffect` is unmounted.
## What is the new behavior?

While debugging #28186, Maria and I identified that Ionic's lifecycle
event listeners (`ionViewWillEnter`, etc.) were being registered
multiple times on the same `.ion-page` element. This resulted in
problematic behavior, where a user's implementation of our lifecycle
hooks, would execute their callback multiple times.
```ts
useIonViewWillEnter(() => {
// This is called 2x for every time the `ionViewWillEnter` event is emitted (in React 18, dev mode)
console.log('hello world');
});
```
When the Ionic lifecycle event listeners are registered in React, we
bind the scope of the class to the callback function. When removing the
event listener we additional use the `.bind` syntax.
```tsx
componentDidMount() {
element.addEventListener('ionViewWillEnter', this.ionViewWillEnter.bind(this));
}
componentWillUnmount() {
// This creates a new instance of the function to remove! It doesn't remove the original event listener.
element.removeEventListener('ionViewWillEnter', this.ionViewWillEnter.bind(this));
}
```
The `.bind` method returns a new instance of the function. This means in
the implementation we are creating a new instance of the function when
both adding and removing the event listener - resulting in the
`removeEventListener` to never remove the original event listener.
This behavior only occurred in React 18 in dev mode, as a result of the
mount/unmount behavior running 2x for `useEffect` hooks.
## What is the new behavior?
<!-- Please describe the behavior or changes that are being added by
this PR. -->
- Ionic lifecycle event listeners are removed from element references
when they are unmounted.
- User's lifecycle callback methods are only invoked once per event
emission.

@liamdebeasi Sorry for replacing the previous PR. I only copied the main
branch to my fork so I couldn't rebase properly. I am unfortunately not
extremely familiar with Github.

## What is the current behavior?
<!-- Please describe the current behavior that you are modifying. -->
When one modal is added and another modal is removed, the modal that is
removed does not account for the newly added modal when updating the
overlay context in React. As a result, the inner contents of the newly
added modal is not mounted.
We originally tried to fix this in
https://github.com/ionic-team/ionic-framework/pull/24553, but the fix
was not complete. While storing the latest information in a React ref
was correct, the way we updated the ref was done in a way such that data
was still stale.
In particular, the `overlaysRef` is updated whenever `IonOverlayManager`
is re-rendered. State updates are batched, so updating the state twice
in quick succession does not necessarily result in 2 separate renders.
## What is the new behavior?
<!-- Please describe the behavior or changes that are being added by
this PR. -->
- We need to make sure the ref is updated synchronously before any
render so that `addOverlay` and `removeOverlay` always have access to
the latest data.
- Added a test

`onDidDismiss` and `onWillPresent` will fire twice when having a manual
binding in your implementation for inline overlays.
e.g.:

<IonAlert onDidDismiss={() => console.log('hello world')} />

Will result in:
> hello world
> hello world

The sync script for the React package is out of date. It will
unintentionally delete the symlink directory of the build output from
`core/`, which breaks the build for the package during local
development.
