fix: update then child object layout changes

[T-Wizard]

fix that update in child listboxes did not update the filterpane Selection & Header for folded listboxes and anything that affected layout & if the listbox should be collapsed (ex: Collapse Listbox setting)

some rist of performance degrade as there are more update that make it re-render

Would be great with unit tests too, but could be added later I guess. Nice solution!
