I am not sure this is exactly true. I have a behavior for all my database forms, so that I can code generally for all forms, while also putting form specific code in the actual card script. It is my recollection that if I send to the card, and the card does not handle the message, or passes the message, then the behavior script gets it. 

To test this, I scripted a handler in the stack script which popped an answer dialog. I then sent the handler to the current card, and the stack script got it.

If that is the case, then you should submit a comment in the dictionary for dispatch. I looked and there does not seem to be any mention about switching contexts or having the target object's stack become the defaultStack.
