Task execution for host within multiple host groups and different aliases

[Thms Hmm]

I'm struggling with hosts that belong to multiple host groups and have different aliases. The problem i'm facing is, that if i try to execute a task on group "all_hosts" where each group belongs to, the task is executed for each alias and not on a ansible_host basis.

I expect that the task is only executed once for the host. Independent of the alias.

The inventory i'm using looks like this:

[all_hosts:children]
group1
group2

[group1]
host-alias-1-group-1 ansible_host=host-1

[group2]
host-alias-1-group-2 ansible_host=host-1


I can create the all_hosts group like this:

[all_hosts:children]
host-alias-1-group-all ansible_host=host-1

...but that seems like a workaround. Any advice would be appreciated.
