What is the situation?

I just put the default code into the official volume project template:

import SwiftUI
import RealityKit
import RealityBounds

struct GameWindow: View {
  var body: some View {
    RealityView { content in
      content.add(BoundsVisualizer(boundes: []))
    }
  }
}

But the bound box does not display on the simulator:

I use debug visualize to check, the bound box is put on the right position but I just can't see them:

The project to reappear this bug
