The wrong RNA pointers were passed (passing the root ones instead of the
ones actually owning the rna-path-resolved property).
This was likely a harmless mistake, since it only affected RNA
collections of IDs, afaik we currently don't have many (if any) of these
in non-ID RNA structures. The children collections and objects in a
Collection data-block RNA structure e.g. were not affected.
But the potential consequence of that bug would have been missing
automatic detection of some needed liboverride resyncs.
