           Summary: Constraint Validation API tooLong property incorrect
                    with prefilled value
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Macintosh
        OS/Version: Mac OS X 10.8
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: Forms
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: tj.vantoll at gmail.com


Per the spec (http://www.whatwg.org/specs/web-apps/current-work/#constraint-validation-api) a form control's validity.tooLong property should be "true if the element's value is longer than the provided maximum length; false otherwise."

However, if you have an input that has a preset value that is greater than its maxlength the tooLong property will still be false:

<input id="foo" type="text" maxlength="1" value="AB">
<script>
    document.getElementById('foo').validity.tooLong; //false
</script>

Furthermore when this element is in a form that form is allowed to submit - http://jsfiddle.net/tj_vantoll/x5LEn/.
