Description

When using a CollectionView with ItemSizingStrategy="MeasureFirstItem" in HorizontalList or HorizontalGrid layouts, the sizing behavior does not work as expected. Items are not sized consistently based on the first item, leading to layout issues .

Steps to Reproduce

1. Run the attached sample ItemSizingStrategySample 2.zip
2. Set ItemSizingStrategy as MeasureFirstItem for Horizontal List.
3. Observe the layout, items are not sized uniformly, and their widths vary based on their content.
4. Observe the behavior for Horizontal Grid also.

Expected Behavior: The CollectionView should size all items consistently based on the size of the first item in the collection

Actual Behavior: In HorizontalList and Horizontal Grid layout, items are not sized uniformly, and their widths vary based on their content.
