Change Details

==== Context Currently, a sub-reference is distinguished by the `MWReferenceNode` `mainRefKey` property. This property is null for a normal reference, but for a sub-reference it holds the "list key" of the main ref. In order to make this linkage less fragile and less dependent on a "synthetic" main ref node, we will replace this property with the `listIndex` of the main ref's `InternalItemNode`. We anticipate that this will eliminate the need for the synthetic main ref. It's also a small step towards deprecating the keyIndexes and listKey mechanisms, while still limiting the scope of the change to only affect sub-references. Especially watch out for copy-paste use cases, which involve merging and regeneration of parts of the InternalList. Does the InternalItemNode survive these transformations?
