XF 2.3 The Font Awesome badges do not display after the user's rank.

[AndryOsminin]

Hello everyone. I managed to change the node icons through Extra.less, as shown in the first screenshot. Now I want to add icons after user ranks. However, I can't get it to work since most of them don't display. I can only set basic icons, which is strange considering I easily set any icons for nodes.

Can you help, maybe I'm doing something wrong?? Here's what I'm adding in the rank input field to display icons:

Novice <i class="fa--xf fal fa-user fa-fw"><svg xmlns="http://www.w3.org/2000/svg" role="img"><use href="/data/local/icons/light.svg#user"></use></svg></i>

This icon displays, but if I change it to something else, like a gun icon, it won't show up
