Summary:
The prototype cell of a UICollectionView as specified in a storyboard does not take into consideration the CGSize retuned by a UICollectionViewDelegate at

collectionView(collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAtIndexPath indexPath: NSIndexPath) -> CGSize

Steps to Reproduce:
1. Create a Single View Application
2. Open the Main.storyboard
3. Drag a UICollectionView
4. Set a reuse identifier for the single UICollectionViewCell
5. Create a subclass of UICollectionViewCell, implement required init(coder:) and set it as the class for the prototype cell
6. Have the provided ViewController implement UICollectionViewDelegate, UICollectionViewDataSource to return 1 cell with the same reuse identifier
7. Specify a sizeForItemAtIndexPath other than the default cell size in the prototype cell.

Expected Results:
When init(coder:) is called, the cell's bounds' size to have the value specified in sizeForItemAtIndexPath

Actual Results:
The cell's bounds' size is set to the prototype's cell size

Version:
iOS 8.4 SDK, iOS 9.2 SDK, Xcode 7.2.0, Xcode 7.2.1 

Notes:
Workaround, use UICollectionView.registerClass(:forCellWithReuseIdentifier:) to register the cell instead.

Configuration:
iPhone 4S, iOS 9.2.1 | iPhone 5, iOS 8.4.1 | Xcode 7.2. Simulator (iPhone 4S, iPhone 6 Plus)
