Comment 3 for bug 1203329

The panel in question is the MapView - smooth_move (see scripting/ui.lua) holds to a local reference of it. There are a bunch of ways to solve this:

1) do not hold on to a MapView instead always recreate it in the lua code when needed.
2) add persistence support for MapView only (simple to add in the lua code, but a test will be needed too).
3) forbid saving/user input during scrolling.

I think 2 is the best solution and solves 90% of the ui-is-not-persistable problem. 1 is easiest. 3 is probably not such a good idea.
