IonModal unable to handle dismiss (onDidDismiss)

I have a simple modal with controlled `isOpen` state:

` { alert('DID') }} presentingElement={presentingElement}>`

On iOS the modal is dismissable with a gesture due to `presentingElement`, which needs to be handled.
`onDidDismiss` does not fire.
Documentation is saying that this returns a promise. I tried to handle it via `ref.current.onDidDismiss().then(...` but no avail.

Start by reproducing the controlled IonModal example with isOpen, presentingElement, and onDidDismiss on iOS. Check the gesture-dismiss path and compare it with the documented ref.current.onDidDismiss() promise behavior. Done means the callback or promise reliably reports a gesture dismissal.
