Only when the zone is unbypassed does it report on the current state again which might be different to what the initial state was. In short, every zone you unbypass will report it's state to Cbus be it the same or different from the initial state when bypassed. The only other message you will get on Cbus is if you disarm the system with a bypassed zone. When you disarm the state will change to non-isolated.
I agree with you Ingo regarding the Zone state. I have a web page on an automation controller that shows all the zones (state and isolated). The Zone state (0/208/21) are updated as expected.

However,  bypassed/isolated (0/208/20) is only set at the bypass stage and results in an inaccurate display of the zone bypass status.
What I am trying to say is, it seems  (0/208/20/x) is set when a zone x is bypassed, but not cleared when the zone is unbypassed.
