Summary: changelog: [internal] `parentNodes` may be nil in case `DiffClampAnimatedNode` was not setup correctly. In this case, let's just noop and warn rather than throw redbox. This is not necessary but makes the code safer in world where native animated is invoked by new and old architecture at the same time (pre-bridgeless).
