What you describe is how it SHOULD work, but it seems like we've had a regression, as I'm seeing the same behavior as you. This is a perfect example of why the Quantum team is going to use the Bug Squashing day next thursday to focus on improving unit + integration tests so we have better code coverage. Hope you can join! The fix is actually pretty easy, but its too late to get it into E-3, so I will commit it for E-4.
