Unfortunately, that is a limitation of Fedora's update release habits,
which have changed again with the end of Fedora Extras some years ago.
In the repositories, a new stable update replaces the previous stable
update. Older update packages are only available if you use something
like yum-plugin-local.

So, typically "yum history undo …" works better in conjunction with
updates-testing repo enabled and frequent updates. In that case you can
revert to the last stable updates. "yum downgrade …", on the other hand,
would attempt downgrading to old packages from the "fedora" release repo.
