setThing not creating blank nodes included within a Thing

I am experiencing issues with setThing ignoring blankNodes entirely. The internal dataset changelog will have no quads for the blank node. This seems to be expected behavior according to this line;
https://github.com/inrupt/solid-client-js/blob/main/src/thing/thing.internal.ts#L121
which removes them from the "additions". Removing this filter fixes the issue without any failed tests, so I am not sure why it is being used?

I've created a unit test in this fork:
https://github.com/Maximvdw/solid-client-js/commit/d2227cf33cbebc47bd80db075d3dc07fb6f9ca74

The unit test creates a mock object:

const mockThing3: ThingPersisted = {
    type: "Subject",
    url: mockThing3Iri,
    predicates: {
      ["https://arbitrary.vocab/predicate"]: {
        namedNodes: ["https://arbitrary.vocab/object"],
        blankNodes: [
          {
            ["https://arbitrary.vocab/blanknode/predicate"]: {
              namedNodes: ["https://arbitrary.vocab/blanknode/object"],
            },
          },
        ],
      },
    },
  };

When using setThing only one quad will be added (the named node) which is verified
with the test line at https://github.com/Maximvdw/solid-client-js/commit/d2227cf33cbebc47bd80db075d3dc07fb6f9ca74#diff-b64c1976153ad9380bdd23fab11663989148669f7f2e99cbd3faf7342a687b34R600

Is this intended behavior for setThing?

Start at setThing and inspect the additions filter in src/thing/thing.internal.ts around line 121. Review the linked unit test commit and its blank-node fixture, then run the relevant tests to confirm whether setThing should add quads for nested blank nodes as well as the named node.
