    iconGrid: Fix nonsense condition
    
    Just like the "in" operator in the previous patch, "instanceof" has
    a lower precedence than negation, resulting in the nonsense condition
    of "true instanceof BaseIcon".
    
    Add parentheses to get the intended behavior.
    
    Spotted by eslint.
