In a useSubscribe query, I have the following:

const countWithoutIndex = (
    await txn
        .scan({
            limit: 1,
        })
        .entries()
        .toArray()
).length;

const countWithIndex = (
    await txn
        .scan({
            indexName: "foo",
            limit: 1,
            start: {
                key: ["bar"],
            },
        })
        .entries()
        .toArray()
).length;

I observed that countWithoutIndex is always 1 (respecting the limit option as expected), but countWithIndex is not 1. It seems that the scan iterator does start at the provided index value ("bar"), but it doesn't stop at the given limit.
