title: Collection View Compositional Layout with estimated height not working
body: <p>I want my app to be optimized for every accessibility options including the text size.</p>
  
  <p>I made a collectionView layout based on sections with a compositional layout. So I need my cell's height to grow with it's content. I thought using <code>.estimated(constant)</code> would do the job but it doesn't seem to work. The inner constraints seems good to me.</p>
  
  <p>Here is the layout I'm working with :</p>
  
  <pre><code>let size = NSCollectionLayoutSize(widthDimension: .fractionalWidth(0.42), heightDimension: .estimated(90))
  let item = NSCollectionLayoutItem(layoutSize: NSCollectionLayoutSize(widthDimension: .fractionalWidth(1.0), heightDimension: .estimated(90)))
  item.contentInsets = NSDirectionalEdgeInsets(top: 5.0, leading: 12.0, bottom: 5.0, trailing: 12.0)
  let group = NSCollectionLayoutGroup.vertical(layoutSize: size, subitem: item, count: 1)
  let section = NSCollectionLayoutSection(group: group)
  section.contentInsets = NSDirectionalEdgeInsets(top: 0.0, leading: 6.0, bottom: 0.0, trailing: 0.0)
  section.orthogonalScrollingBehavior = .groupPaging
  </code></pre>
  
  <p>When I set a higher text size on the accessibility settings here is what happens :</p>

  <p>The cell is supposed to contain 2 labels here is the autoLayoutConstraints :</p>
  
  <pre><code>    NSLayoutConstraint.activate([
          self.titleLabel.topAnchor.constraint(equalTo: self.container.topAnchor, constant: 10),
          self.titleLabel.leftAnchor.constraint(equalTo: self.container.leftAnchor, constant: 20),
          self.titleLabel.rightAnchor.constraint(equalTo: self.container.rightAnchor, constant: -20)
      ])
  
      NSLayoutConstraint.activate([
          self.subtitleLabel.topAnchor.constraint(equalTo: self.titleLabel.bottomAnchor, constant: 10),
          self.subtitleLabel.leftAnchor.constraint(equalTo: self.container.leftAnchor, constant: 20),
          self.subtitleLabel.rightAnchor.constraint(equalTo: self.container.rightAnchor, constant: -20),
          self.subtitleLabel.bottomAnchor.constraint(equalTo: self.container.bottomAnchor, constant: -10)
      ])
  </code></pre>
  
  <p>Thanks in advance for your help.</p>
