To be honest so far I was viewing this as intended and desirable
behavior. Now that you mention it I can see why the one you'd
prefer would also make sense (albeit I'm not sure now which one
is the better one).

As to the odd difference in behavior - I have no idea (i.e. would
need to try this out and perhaps debug it, but since you're on it
I guess I'll leave it to you).
