Using CollectionView for a list with items that can expand/collapse on tap doesn't properly resize on iOS

[helixaril]

Description

I am working on an application, which me and my team are porting from Xamarin.Forms to MAUI. In the Xamarin app we implemented an expansion list using CollectionView. The list would have several items and whenever you would tap on one it would expand the item. The expanded item could contain text, images, buttons etc.

However, now in MAUI, the same code using CollectionView works perfectly on Android, but on iOS whenever I collapse an item the size doesn't change back to the original one.

I attached two images to showcase it. In the first one you can see how the list should open when first accessing the page containing it (iOS left, Android right).

On the second image I collapsed the first item in the list and as you can see for iOS it doesn't resize

The size of the item goes back to normal only if I scroll past that item and then scroll back

Verified this issue with Visual Studio 17.11.0 Preview 2.0 (8.0.60 & 8.0.40 & 8.0.21 & 8.0.3). Can repro on iOS platform with sample project.

We see a similar issue in our app with MAUI 8.0.14

We have found a workaround in the end. Instead of using a collectionview we have used a stacklayout inside a scrollview

Performance with StackLayout using BindableLayout is way bader than with the CollectionView.
Also: using BindableLayout crashes the app with a certain list size.
