The function name is wrong.  This code is not related to mouse capture. The
function name should be "fieldDidChangeValueByKeyboard" or something.

Also, we don't change the input value yet at this line. We should call the
callback after handleKeyboardEvent and after defaultKeyboardEventHandler.

         if (!isDisabled() && !isFieldOwnerDisabled() && !isFieldOwnerReadOnly()) {
             handleKeyboardEvent(keyboardEvent);
             if (keyboardEvent->defaultHandled())
