I get this warning in the console, after I installed CustomUI yesterday. Also, on recent versions of Chrome, Firefox and Edge (tested on iOS, Android, OSX and Windows), "icon_color" is not working.

EDIT: OK, this "icon_color" problem seems to be "half a problem". It works, but sometimes. :D And I can't understand why it doesn't work, when it doesn't work, and vice versa. Same browsers, same computers, same phones. Cache disabled on computer browsers .. :\
