In iOS, CollectionView row does not shift down if row above it resizes

[grantlogsdon1]

Description

In iOS, when the size of a row in a CollectionView increases, it appears behind the rows below it. WinUI/Android work as expected where the rows shift down as to not overlap the resized row.

More Context:
The Data Template for my CollectionView contains a Grid with one row defined as ‘*’. The row contains multiple columns with controls. One of the controls is a custom control that that functions like a ComboBox (since there is no built in MAUI control for this). This ComboBox is what leads to the requirement that the row have a dynamic height. It consists of a Entry and a CollectionView stacked on top of each other. The user is able to type into an entry field and CollectionView appears below the entry with filtered results based on the users input.
When the ComboBox's CollectionView appears, the whole row grows to accommodate the new height (I have not found a reliable way to make it just overlap on top of the rows below it).

Steps to Reproduce

1. Create a CollectionView. Bind to a list with multiple items, so that CollectionView will have multiple rows.
2. Add a Grid into the CollectionView data template with one row defined as '*' or 'Auto' (Both have the same result)
3. In the Grid, add a control that can be resized by an action performed in the app. I have a CollectionView that will get populated with labels
4. Perform action to cause collection view row to grow
