AFAIK there is no mention anywhere that this behaviour is intended (if thats the case, then I will change this to a FR immediately). And while I appreciate your help here on the forum, you are no dev to be certain about it, or am I wrong?
Just because Cubase always behaved in a certain way, does not mean that it is intended or should be this way (especially when it is not a feature, but a limitation). I opened quite some issue reports in the past (about limitations which where always there), and the support staff was happy that I took the time to show them exactly what was wrong.
