Role ignores check mode / files changed in check mode

[divialth]

The role in the version 1.1.6 changes the configuration, even if it is only running in check mode.
(ansible collection "fedora.linux_system_roles" 1.120.2)

Test

Config

bootloader_settings:
  - kernel: ALL
    options:
      - name: console
        value: ttyS0
        state: present

cp /etc/default/grub /tmp
ansible-playbook -u xxx -i inventories/systems  playbook.yml --diff -C

Output:

...
TASK [fedora.linux_system_roles.bootloader : Ensure boot loader settings] **********************************************************************************************************************************************************************************************************
changed: [xxxxxxxx]
...

So far so good, but if we now look at the file, we see it was really changed on disk, even the role was run in check mode:
