Just checking as I'm not sure how to start manual testing and trying to work out if theres any issue with this

We have slightly different semantics for what isPresented means between v3 and v4

In v3 you implemented isPresented via isAttachedToWindow
Here the presented semantics are whether the view is shown to the user, it can be dismissed if its preload and still kept in the view hierarchy
