This feels a bit gross but is required to make sure the loading spinner in a nested row is properly updated when its loading state updates

For now I've preserved the previous behavior of just focusing the tree if the loader disappears, but ideally we'd do something like useListState and useGridState where it looks for the closest focusable row as a substitute. Will handle that update upon refactoring some of that logic as noted in https://github.com/adobe/react-spectrum/pull/8326/files#r2116825740
