And how exactly do you suggest it be fixed? How can "heavy breathing" be removed without building a time machine and going back to reshoot the scene?
It's been years since I watched ESB simply because I'm waiting to watch this version with a clear mind so to speak, so you could be right that it looks weird or that the continuity isn't right. I honestly don't remember, but I don't see how something like that can be fixed if it indeed needs fixing.
