The native checkValidity() method and jQuery's is method for the selectors ':valid'/':invalid' are returning wrong results, if you set an invalid value to a disabled form field and then enabling it.

I created a testcase here: http://jsfiddle.net/9bsZ9/

1. Create a disabled and required form field
2. Set this field to an invalid value through script
3. Set disabled to false

-> checkValidity should return false, but returns true. I'm not sure, why matchesSelector and jQuery.is are returning different values, but should also be looked into.
