Force parent ListenerListInsts to rebuild.
Force parent ListenerListInsts to rebuild.

Without this change, it is possible (and, in fact, nearly guaranteed) for lists to rebuild endlessly if a parent list is marked as needing a rebuild but never actually read. This change forces the parent list(s) to rebuild as well, resulting in a significant performance increase and smoother framerate due to greatly reduced GC activity.
