The defaultAction of an Exception should be evaluated in the Context of the method that signalled the Exception.

Thus, an enclosing exception handler (on:do:) upper in the stack shall still be active whenever the defaultAction raise another exception.

This documents why simply deactivating the exception (see handlerActive, tempAt: 3, of #on:do:) is not the right way to fix handling of nested exception.
