Actually, that specific problem was addressed long ago based on feedback  
 from us:

"Constraint validation: If an element has a maximum allowed value length,  
and its dirty value flag is true, and the code-point length of the  
element's value is greater than the element's maximum allowed value  
length, then the element is suffering from being too long."

The "dirty value flag" is only true when the user has edited the control.
