The enum items propagation mechanism for Menu sockets makes a local copy of item pointers to propagate between node group inputs and interface definitions. In case these items are not used (e.g. because they are already shared with the socket) the local copy must still be released to avoid leaking the memory. This only happens with more than 4 enum items, because of the internal default buffer for `Vector`. Pull Request: https://projects.blender.org/blender/blender/pulls/135226
