Describe the bug

Fontawesome icons arent't displayed correctly

To Reproduce

Open Configuration -> Access Control -> Select a random role

or

Press any safe button -> the alert to confirm the change will have the same problem

Expected behavior

Hi,

install the fileinfo extension for PHP and it should work.

[knbrende]

You were right: I installed the extension and the icons are shown properly now.

Did I miss this part in the docs?

Nope, it's missing.
