I think we can make it more robust by refactoring it a bit, setting the "supports item expanding" property in KStandardItemListView, and answering the question if the layout supports it in a virtual function. Then we can just do everything that is needed if the state of that property chanes in onSupportsItemExpandingChanged(), and safely make DolphinItemListView::onItemLayoutChanged() call the base class implementation (which fixes the bug):
