iOS 26 Spacer does not work in keyboard toolbar (however labored on iOS 18)

I have to structure just a few textual content & picture buttons on keyboard toolbar, and wish to insert spacers to evenly lay them out. This labored on iOS 18. Nevertheless, on iOS 26, all are cluttered collectively. See image:

This is a minimal repro you may mess around with:

import SwiftUI

struct ContentView: View {
  @State var textual content: String = ""
  var physique: some View {
    NavigationStack {
      Listing {
        TextField("Click on Me", textual content: $textual content)
        
        Textual content("Hiya, world!").font(Font.system(measurement: 32))
        Textual content("Hiya, world!").font(Font.system(measurement: 32))
        Textual content("Hiya, world!").font(Font.system(measurement: 32))
        Textual content("Hiya, world!").font(Font.system(measurement: 32))
        Textual content("Hiya, world!").font(Font.system(measurement: 32))
      }
      .toolbar {
        ToolbarItemGroup(placement: .topBarLeading) {
          Button {
            
          } label: {
            Textual content("Toggle")
          }
        }
      }
      .toolbar {
        ToolbarItemGroup(placement: .keyboard) {
          keyboardButtons
        }
      }
    }
    .navigationTitle("Hiya")
  }
  
  @ViewBuilder
  personal var keyboardButtons: some View {

    HStack {
      SUITextButton("Button") {}
      Spacer()
      
      
      SUIImageButton(
        picture: UIImage(
          systemName: "chevron.left",
          withConfiguration: UIImage.SymbolConfiguration(pointSize: 32, weight: .common, scale: .small)
        )!,
        enabled: true
      ) {}

      Spacer()


      SUIImageButton(
        picture: UIImage(
          systemName: "chevron.proper",
          withConfiguration: UIImage.SymbolConfiguration(pointSize: 32, weight: .common, scale: .small)
        )!,
        enabled: true
      ) {}

      Spacer()
      SUITextButton("Button") {}
    }
  }
}

#Preview {
  ContentView()
}

public struct SUITextButton: View {
  
  personal let title: String
  personal let motion: () -> Void
  personal let enabled: Bool
  
  public init(_ title: String, enabled: Bool = true, motion: @escaping () -> Void) {
    self.title = title
    self.enabled = enabled
    self.motion = motion
  }
  
  public var physique: some View {
    Button(title, motion: motion)
  }
}

public struct SUIImageButton: View {
  
  public init(picture: UIImage, enabled: Bool, motion: @escaping () -> Void) {
    self.picture = picture
    self.enabled = enabled
    self.motion = motion
  }
  
  personal let picture: UIImage
  personal let enabled: Bool
  personal let motion: () -> Void
  
  public var physique: some View {
    Button(motion: motion) {
      SUIImage(
        uiImage: picture,
        // Because it's within a button, will probably be blue when enabled, and grey when disabled.
        rendering: .systemTint)
    }
  }
  
}

public struct SUIImage: View {
  
  public enum Rendering {
    case systemTint
    case customColor(coloration: UIColor)
    case authentic
  }
  
  
  personal let uiImage: UIImage
  personal let rendering: Rendering

  public init(uiImage: UIImage, rendering: Rendering) {
    self.uiImage = uiImage
    self.rendering = rendering
  }
  
  public var physique: some View {
    
    let width: CGFloat = 18.0 + (2.0 / 3.0)
    let top: CGFloat = 26.0 + (2.0 / 3.0)
    
    Picture(uiImage: uiImage)
      .renderingMode(.template)
  }
}

Setting UIDesignRequriesCompatibility flag labored, however I want glass impact for different elements of my app (and I believe it seems higher with glass impact above keyboard). In order that’s not an possibility.
