This issue was already opened here:

  https://github.com/ansible/ansible-modules-extras/issues/3447

I will be very happy if you will take a look and tell what you think
about the proposed fix.

I've opened an issue here:

  https://github.com/ansible/ansible-modules-extras/issues/3555

Feel free to comment there any additional requests regarding that issue.

I've opened following issue:

  https://github.com/ansible/ansible/issues/18650

I will work on it, feel free to comment any ideas there.
