UISearchController prevents button tap inside UICollectionViewListCell

Good day to all, I have a weird problem with tapping on a button inside collection view cell when search results controllers is active.

So, I'm initializing searchController like this:

private let searchController = UISearchController(searchResultsController: nil)

In my viewDidLoad():

 searchController.searchResultsUpdater = self
 searchController.obscuresBackgroundDuringPresentation = false
 searchController.definesPresentationContext = true
 navigationItem.searchController = searchController

Making data source:

private func makeDataSource() -> DataSource {
    let cellRegistration = UICollectionView.CellRegistration(
                 handler: CellProvider().cellRegistrationHandler
    )    
    return DataSource(collectionView: collectionView) {
            (collectionView: UICollectionView, 
             indexPath: IndexPath,
             item: IngredientViewData) in
            
             return collectionView.dequeueConfiguredReusableCell(
                 using: cellRegistration,
                  for: indexPath,
                  item: item
            )
        }
    }

Nothing fancy. In the CellProvider:

var buttonConfiguration = addButtonConfiguration(for: item)
buttonConfiguration.tintColor = .systemBlue
cell.accessories = [
     .customView(configuration: buttonConfiguration),
     .disclosureIndicator(displayed: .always)
 ]
cell.contentConfiguration = contentConfiguration

private func addButtonConfiguration(for item: IngredientViewData) -> UICellAccessory.CustomViewConfiguration
{
   let symbolName = item.isSelected ? "checkmark.circle" : "circle"
   let symbolConfiguration = UIImage.SymbolConfiguration(textStyle: .title1)
   let image = UIImage(
      systemName: symbolName, 
      withConfiguration: symbolConfiguration
   )
  let button = AddButton()
  button.addTarget(
      nil,
      action: #selector(IngredientsCollectionViewController.didPressDoneButton),
      for: .touchUpInside
  )
  button.id = item.id
  button.setImage(image, for: .normal)
  return UICellAccessory.CustomViewConfiguration(
            customView: button, placement: .leading(displayed: .always))
 }

Pretty basic setup. Simple button and selector to the view controller. Tapping works fine when searchController is not active. And if it is, then IngredientsCollectionViewController.didPressDoneButton won't be called.

What am I missing?
