Incorrect CollectionView height inside VerticalStackLayout

[lucasbrahm]

Description

With a CollectionView inside a VerticalStackLayout, it is expected that the CollectionView will grow with the remaining space available of the page and the itens of the collection should be scrollable.

But what is happening is that CollectionView is growing until the height size to display all itens, being this height greater than the page size, making it impossible to scroll to the last element.

Specifying the height (HeightRequest) of the CollectionView is a workaround, but I want it to grow with the remaining space.

Steps to Reproduce

1. Create a page with a VerticalStackLayout and add CollectionView inside of it.
2. Add a lot of itens the CollectionView (enough to need to be scrollable).
3. As CollectionView grew greater than page height, it is not possible to scroll to the last element.

Afaik VerticalStackLayout is supposed to grow indefinitely (it sets no vertical constraint on the children. To achieve what you probably want, a Grid must be used, or you can simply put the collection view as page content.
