Why is the wrong field value shown in the error message when using jQuery (remote) validation?

Question

I'm using the jQuery validation plugin in a very similar manner to the Remember The Milk demo.

$("#registrationForm").validate({
  rules: {      
    email: {
      required: true,
      email: true,
      remote: '<%=Url.Action(...) %>'
    },        
  },
  messages: {
    email: {
      required: "Please enter an email address",
      email: "Please enter a valid email address",
      remote: jQuery.format("{0} is already in use")
    }
});

The first time an invalid email (e.g. [email protected]) is submitted, the error message is as expected. However, if I then enter another invalid email (e.g. [email protected]), the validation plugin still displays "[email protected] is already in use."

I've traced the parameters that are reaching the controller specified in Url.Action call and they are definitely correct (i.e. "[email protected]" is sent as the email address when that is what is entered in the field).

Has anyone else run into this or a similar issue using the jQuery validation plugin?

The user name field on the Remember the Milk demo fails in the same way (when entering user names 'Peter' and 'George'), so you've probably found a bug in the plugin.
