Hmm, yes, you're right - looks like that never got finished off.

The idea was to be able to keep track of what's changed at each level of
the stack, so that when we pop the stack we're able to update only those
bits of state which actually changed in the corresponding push.

But at the moment we start it off as kQ3ViewStateAll, and never keep
track of things as they're added: so end up with clearing everything on
each pop.

Do you want to fix it up to work properly, or log a bug so that we know
it could be improved?
