Summary:
we only include in the inspector hierarchy the sections which are visible on screen. If as a result of a UI change the hierarchy of visible sections changes (for example when scrolling to a section that wasn't previously visible) this forces the section hierarchy to be recreated.
passy not sure if there's an easier way of making the children of a node invalidate, let me know if you have any suggestions
