[Bug]: event.preventDefault() doesn't work on iOS

[emawby]

@kamil-floqsta In order to not display the notification you just call event.preventDefault();
If you would then like to display the notification after delaying the default display you call event.getNotifications.display();
If you never want to show the notification do not call display

@emawby Unfortunately it doesn't work. Here is a code sample:

OneSignal.Notifications.addEventListener(
    'foregroundWillDisplay',
    (notificationReceivedEvent: NotificationWillDisplayEvent) => {
      const notification = notificationReceivedEvent.getNotification();
        if (
          // some condition
        ) {
          notificationReceivedEvent.preventDefault();
          return;
        }
      }
      notification.display();
      }
  );

The listener receives a notification, then notificationReceivedEvent.preventDefault() is called but after about ~10 seconds the notification is displayed anyway.

@emawby I turned on logs with LogLevel.Verbose
And here is the Xcode outcome for the notification with preventDefault():

@emawby Even if e. preventDefault() is removed the loggs says it was called:

2023-10-27 12:10:15.873749+0200 PROJECT_NAME[86156:18319475] VERBOSE: OSNotificationWillDisplayEvent.preventDefault called.
