Frustrating isn't it - they are "uncredited" for a reason... it does seem a little ridiculous. Much like an extra adding themselves to a cast list on IMDB - we get them too.
I think it would be weird to exclude them, especially as the scene takes up (virtually?) the whole screen for a few seconds -- it's not as though it's on in the background.
However, I reimported the film so that they would be at the bottom.
