When PagerSnapHelper calculates the distance between the center of a View and the center of RecyclerView, it only respects RecyclerView's padding when clipToPadding is set to true. However, even when clipToPadding is set to true, the center should be in the middle between the padded edges, not in the middle between the actual edges.

The reasoning is that the padding defines the content rectangle, and whether or not children's pixels are clipped to that rectangle or not doesn't change the semantics of that rectangle.

Consider for example a horizontal ViewPager2 that has unequal padding on the left and the right. When it is in idle state, a page exactly fills the rectangle described by the inner edge of the padding, so the page looks to be off-center by design. When snapping kicks in (e.g., because of a swipe), the page to which it is snapping should end up in that same "off-center" position, exactly matching the rectangle described by the inner edge of the padding, regardless of the value of clipToPadding.
