CachedFilesMixin.patterns should be case-insensitive
    
    
    
      
      
      
        
According to [1], all CSS syntax is case-insensitive within the ASCII range (i.e., [a-z] and [A-Z] are equivalent), except for parts that are not under the control of CSS. So, it seems like re.compile(pattern, re.IGNORECASE) is a valid and not so restricting way to go.
