loose harness on opening??

I was just wondering if this has happened to anyone else? I don't think I would have fell out of the harness without both stoppers blowing at the same time. I also have both of the black bungee leg strap holders that came with the harness. Also I was wondering if anyone does anything to prevent this from happening like maybe any extra elastic band?
Thanks for your thoughts and ideas.
