This is actually present in all sidebar widgets, since the navigation system only understands locations in main view areas, so undoing an operation (which causes navigation) will focus the main view instead. Fixing this correctly will involve a rewrite of the navigation/location system, or a bunch of hacks to handle type view specifically.
