The behavior of an object is treated the same as any other property.
If you set it and save the stack, it's permanent. Until changed. If
you set it to empty, you're essentially clearing the behavior property
of the object, unlinking the object from its behavior button.

Think of setting or clearing the backgroundcolor of the field. It has
the same persistence characteristics: if you save the stack, it's
saved with the current property value; if you change the setting and
don't save it then the setting disappears when the stack is closed.
