Icons not working

I went to replace icons with personalized ones and half the icons either don't show up or don't work. This really needs to be fixed because being able to use your own icons is a part of customizing your site. I had thought this issue was fixed already but it isn't. My icons are all the same size so no reason why they work in profile stats but not in member toolbar. Or blown up in site toolbar on one theme and super shrunk on another. @Alex T⚜️ @Andrey Yasko
