Perception warnings in State.init

[KirillZholnerovich]

Description

For example, we have ParentFeature and ChildFeature and if we have array of ChileFeature.State in ParentFeature.State it throws runtime perception warning

Code:

@Reducer
 public struct ParentFeature {
    @ObservableState
    public struct State {
        public var items: IdentifiedArrayOf<ChildFeature.State> = [ .init() ]

        //...
    }

    //.......
 }

@KirillZholnerovich I don't think this is a bug in the library and you have not provided a full reproduction for us to evaluate the problem.

It does sound like maybe there could be an observation issue in your application requiring a WithPerceptionTracking view, but we'll need more info to help. Please follow up in the discussion with some compiling sample code!
