Using a template for ansible_host with inventory_hostname breaks with delegation

[Maximilian Gaß]

Hello,

I have a domain that I want to be appended to all hosts in the inventory. To reduce duplication, I thought I'd set ansible_host={{inventory_hostname}}.osf.credativ.lan. 

Unfortunately, this breaks with delegation. Ansible connects to the play host, not to the host I delegated to, because of the template evaluation. I uploaded the inventory, playbook and output to a Gist: https://gist.github.com/mxey/cb5a9e6483f42ca60cbb

I found this issue on GitHub: https://github.com/ansible/ansible/issues/10781. It seems like a related problem at least, but to me it's not clear from the issue status whether it had been fixed or not.

Kind regards
