Rodney, if the need arises we can certainly think of a way to give the account plugin full control over the page (though I'm not even sure it's a good idea: one could ship an account plugin which presents itself as a Google account and fools the user into inserting his Google credentials), but anyway as far as this specific bug is concerned, this is irrelevant.
As I understand, the only thing that needs to be done here is to remove the "Sign in to your Ubuntu One account" message, which comes from the plugin.
