Resolution Note:
This is an intentional design tradeoff.
Native Containers do not support disposal from multiple aliases. These containers aren't reference counted or version tracked outside of the editor. The requested use case would require extra data and logic in standalone player builds which could incur an unnecessary performance penalty.
