git tags not fetched

[aham...@anchorfree.com]

We have a GitHub organization with repos detected and built by github-branch-folder.

I note the following from https://wiki.jenkins.io/display/JENKINS/Git+Plugin for "Version 3.4.0 (July 17, 2017)"

• Because each branch job in a multibranch project will only ever build the one specific branch, the default behaviour for a Git Branch Source is now to use a minimal refspec corresponding to just the required branch. Tags will not be checked out by default. If you have a multibranch project that requires the full set of ref-specs (for example, you might have a pipeline that will use some analysis tool on the diff with some other branch) you can restore the previous behaviour by adding the "Advanced Clone Behaviours". Note: In some cases you may also need to add the "Specify ref specs" behaviour.

I click into my_organization->Configure->Projects under GitHub Organization and enable "Advanced clone behaviors". Instead of an option to _enable_ fetching of tags, there is "Do not fetch tags". It is not enabled, however My builds still do not fetch tags. I tried enabling it in the hopes that it was just a developer forgetting to update the description, but no luck:

How do I get Jenkins to fetch tags?

I'm guessing this is a regression. Created https://issues.jenkins-ci.org/browse/JENKINS-46331
