Section animations are disabled on initialization as holding space
child bubbles will be animated in with their contents already loaded.
Note that the child bubble animation has not yet been implemented.

Also note that this CL also moves animation logic from
HoldingSpaceItemView into HoldingSpaceItemViewsSection since a refactor
has given that class visibility to the parent container of item views.
