Original commit message:

    Fix preview of set entries

    Set entries return an array with the value as first and second entry.
    As such these are considered key value pairs to align with maps
    entries iterator.
    So far the return value was identical to the values iterator and that
    is misleading.

    This also adds tests to verify the results and improves the coverage
    a tiny bit by testing different iterators.
