Listbox items not resized after ROD triggers zk.Widget.prototype.replaceCavedChildren_

Steps to Reproduce

run fiddle
http://zkfiddle.org/sample/3usnnrt/3-Listbox-ROD-render-onSize-missing

Click on the +1 button to add lines

Current Result

When adding a line, the content is marked for rerendering due to ROD.
During rerender, the onSize event doesn't trigger, so the components located inside the listbox follow their "default" size.

Expected Result

Components should trigger onSize to match their current expected size
