     *
     * To properly resolve qualifier parts in the middle,
     * we need to resolve the whole qualifier to understand which parts of the qualifier are package or class qualifiers.
     * And then we will be able to resolve the qualifier selected by the user to the proper class, package or callable.
     *
     * It's possible that the whole qualifier is invalid, in this case we still want to resolve our [selectedFqName].
