Issue details
The size of the CollectionView, including the header and footer, is not rendered correctly on the UI in CV1 but displays correctly in CV2.
Root cause
The GetSize() method calculated the size of the CollectionView based only on its content, ignoring the header and footer sizes. This caused incorrect height or width rendering when a header or footer was used.
Description of Change
The fix calculates the sizes of the header and footer using helper methods, This ensures the total size includes all elements, and the result is adjusted to fit within the CollectionView bounds.
