<a href="https://core.trac.wordpress.org/changeset/36157">[36157]</a> fixed a bug whereby `wp_list_comments()` would not properly recognize
custom pagination arguments. See <a href="https://core.trac.wordpress.org/ticket/35175">#35175</a>. However, it inadvertently introduced
a bug that caused any `$comments` array explicitly passed to the function to be
ignored, when that array was accompanied by pagination arguments that differ
from those in `$wp_query`. We address this bug by moving the logic introduced
in <a href="https://core.trac.wordpress.org/changeset/36157">[36157]</a> inside a block that only fires when no `$comments` array has been
provided to the function.

Props ivankristianto.
