UIConfigurationStateCustomKey with UIContentView.

I'm trying to implement additional UICollectionViewCell's state using UIConfigurationStateCustomKey.

I've already read this post regarding practices for managing custom properties with cells configurations

Seems like I can implement custom state for a UICollectionView's cell.

Here is my implementation of additional state

protocol CustomTypesAccessable: AnyObject {
  var isMoving: Bool { get set }
}

extension UIConfigurationStateCustomKey {
  static let isMoving = UIConfigurationStateCustomKey("com.myApp.cell.isMoving")
}

extension UICellConfigurationState {
  var isMoving: Bool {
    get { self[.isMoving] as? Bool ?? false }
    set { self[.isMoving] = newValue }
  }
}

extension BaseBlockView: CustomTypesAccessable {
  var isMoving: Bool {
    get {
      currentConfiguration.currentConfigurationState?.isMoving ?? false
    }
    set {
      currentConfiguration.currentConfigurationState?.isMoving = newValue
    }
  }
}

My BaseBlockView class:

class BaseBlockView<Configuration: BlockConfigurationProtocol>: UIView, UIContentView {
  var configuration: UIContentConfiguration {
    get { currentConfiguration }
    set {
      guard let newConfiguration = newValue as? Configuration,
         currentConfiguration != newConfiguration else { return }

      currentConfiguration = newConfiguration
    }
  }
  var currentConfiguration: Configuration {
    didSet {
      guard didSetupSubviews else { return }
      update(with: currentConfiguration)
    }
  }

I want to update this state from my view controller in the same way CollectionView can make cell selected

- (void)selectItemAtIndexPath:(nullable NSIndexPath *)indexPath animated:(BOOL)animated scrollPosition:(UICollectionViewScrollPosition)scrollPosition;

So I'm trying to change isMoving value this way:

  let cell = cellForItem(at: indexPath)
    let contentView = cell?.contentView as? CustomTypesAccessable

    contentView?.isMoving = isMoving

Everything works fine in that case, but after reusing cell UICellConfigurationState's isMoving property changes back to false. Is it a UIKit bug?
