Server side validation modification of validating-server-side class

[rprestone]

When using the validating-server-side class to display a ajax-loader style gif whilst the server side validation is being run, it becomes a problem if you have more than one input field using the server side validation. Both input fields display the gif because the whole form gets the validating-server-side class.
Could it be modified to take this into consideration?

Now will the input field also get the class .validating-server-side
