Summary: This test started failing in Xcode 15. It looks like now, the default behaviour of `UICollectionView` is to not perform cell sizing until the next layout pass. As such, the sizing of the cells were invalid until `layoutIfNeeded` is first called. Adding this line to the test brings it back to all of the expected values.
