Port DictionaryBase extensions from ST
Notably, this is missing the equality checking because ST introduces a new type called "ModelBackedItem", which is specifically a type backed by a DictionaryBase item, with extensions. It is very similar to a Wrapper, but has different common utility. If there is a way to migrate that here, then the equality methods can come here as well.
