Attribute selectors validator bug

There is a little bug:-

I used the text-area to check a css rule:-
        table[width=189].nav { width:181px; } 
and got:-
        Parse Error - =189].nav 


I added quotation marks:-
        table[width="189"].nav { width:181px; }  
and got:-
        No error or warning found
        To work as intended, your CSS style sheet needs a correct document parse tree. This means you should use valid HTML.
        Valid CSS informations
                table[width=189].nav { 
                width : 181px;  
        } 
which is precisely what I entered the first time!

Thanks,
