UICollectionView layout is not always invalidated on bounds changes as of iOS 13

Number:rdar://7469191 Date Originated:
Status: Resolved:
Product:iOS Product Version:iOS 13
Classification:UIKit Reproducible:iOS 13
This issue has to do with view controller containment: invalidation for bounds is not happening when custom view controller containing collection view:
1) uses view layout constraints and put into container view controller with layout constraints OR manual frame setting
2) put to navigation controller either directly or in a container view controller

This issue can be reproduced as of iOS 13.

For additional detail see the attached project. Run it on iOS 13 and rotate a device -- notice the collection view has proper bounds while its layout is not updated (stripes are not edge to edge).
