- [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

v8.x

### Current Behavior

Using IonPopover inside an IonModal opened with useIonModal doesn't catch any mouse event.

### Expected Behavior

IonPopover should work the same, regardless of where it is used.

### Steps to Reproduce

Inside a parent component, I have:
```
const [open, dismiss] = useIonModal(ModalComponent);
```

The code of the modal is very simple:
```
function ModalComponent() {
return <>

}
```

Clicking on the first div works, whereas clicking on the second doesn't.
