Instead of changing the display order of the Folder to preserve
the upper left quadrant, we are opting to change the Folder Icon
preview to always show the upper left quadrant.
This means that when adding items to a Folder, the preview items
may change. (They will change when the column size increases).

If the Folder is not closed on on the first page, we animate the
current page items as if they are in the preview.
When the Folder finishes closing, the first page preview items
slide in as the current page preview items slide out.

We want this refactor in O-DR since we will be adding more animations:
- closing from a non-first page (ag/2455887 b/36022592)
- new on-drop animations *if we end up removing the permutation logic.
