However, since the iOS 18 changed the default behaviour from `UIModalPresentationPageSheet` to `UIModalPresentationFormSheet` (it looks vastly different on regular size classes devices, e.g. iPad), for the sake of backward compatibility, we keep the default behaviour from before iOS 18. *This might change in future major release of `react-native-screens`.
