How is DataObjectFactory typing determined?

[tylerbutler]

Consider this declaration:

    private static readonly factory = new DataObjectFactory(
        TableDocumentType,
        TableDocument,
        [
            SparseMatrix.getFactory(),
            SharedNumberSequence.getFactory(),
        ],
        {},
        [
            TableSlice.getFactory().registryEntry,
        ],
    );

According to VSCode intellisense, the inferred type of factory is DataObjectFactory<TableDocument, object, object, IEvent>.

But in this other case:

export const BubblebenchInstantiationFactory = new DataObjectFactory(
    Bubblebench.Name,
    Bubblebench,
    [SharedTree.getFactory()],
    {},
);

In this case, intellisense infers the type as DataObjectFactory<Bubblebench, object, undefined, IEvent>. What is the safest type to use for the generics if I'm not passing registryEntries and runtimeFactory, and not using providers?
