You use the itemsChangeEffect style property to apply
this effect to a List control. The default value of
the itemsChangeEffect style property is undefined,
meaning it does not use any effect.
Because the DefaultListEffect effect grows and shrinks item renderers as it plays,
you must set the List.variableRowHeight property to true
to enable the List control to dynalically change its row height.
