I haven't noticed, but it isn't as easy to notice in V2, at least not how I used it, I'll have to review my logs.
In any case, perhaps you could configure whatever URL(s) are involved in the AJAX part to honor the session but not require one. Then it will passively expose the session if it exists, but just pass through if not. Don't know what that would do to the app or if it would create a security issue, but that's the only possible fix. AJAX just isn't a workable model when the browser doesn't understand the authentication mechanism in use.
