When editing PPAs, software-properties sometimes scrolls back to the top of the list

I use software-properties quite frequently, and particularly extensive use when I upgrade my system (as I have recently done). Whilst working my way through the long list of PPA who's names have been branded with Canonical's infernal 'disabled during upgrade to saucy' appendage, I've noticed that every so often (quite frequently, but not always) when I edit a PPA somewhere down the list, I'll be returned to software-properties main dialogue scrolled back to the top of the list. This, as I am sure you can imagine, is quite annoying, especially when working ones way through a long list of PPA, having to find your way back to where you were, and positively infuriating when coupled with the effects of bug 1261942.
