     *
     * It's possible that the whole qualifier is invalid, in this case we still want to resolve our [selectedFqName].

=== Qualifiers
There is a caveat to comparing versions when it comes to selecting the _highest_ one.
All the rules of <<single_versions#version_ordering,version ordering>> still apply, but the conflict resolver
has a bias towards versions without qualifiers.
