CollectionView contents not sizing correctly after orientation change

[owl-guy]

Description

I have two pages as FlyoutItems in an AppShell. Page 2 contains a CollectionView with Borders as items. When i open Page 2 in portrait mode, switch to page 1, go into landscape view and then go back to page 2, the borders are not sized correctly. Only when i scroll down and then back up again, they suddenly get the right size:
