"flush_handlers task does not support when conditional"...??

Hello,

our latest yum update brought ansible from 2.4.2.0 to 2.7.2 and now we are facing

    [WARNING]: flush_handlers task does not support when conditional

we need the handlers to be flushed at that point, as later tasks rely on previously reconfigured services to be reloaded. The "when" originates from our role definition:

A when statement supplied to flush_handlers has never worked. It was silently ignored in the past, but now has a warning.

There is an open feature request to allow this to work:
https://github.com/ansible/ansible/issues/41313

Hmm. That would explain some random issues that we had in the past with this playbook
