Words longer than 6 letters are not pivoting correctly.

I've found that this piece of code in the pivot() function does not produce the expected results:

        word = '.......' + word;
        
        var tail = 22 - (word.length + 7);
        if(tail > 0) {
          word + ('.'.repeat(tail));
        }

However, the code in the (functional) example works:

        var tail = 22 - (word.length + 7);
        word = '.......' + word + ('.'.repeat(tail));
