Priority of Continuation messages with AAHandled

[AndreVanDelft]

When showing Hello_1_World in the debugger,
I noticed that it currently behaves differently than it used to:

As I recall, after executing Hello, the AAHappened would result in a special
Continuation message at the “;” node. There it would have relatively high priority,
so that the first instantiation of “World” would be excluded.

Currently there seems to be a single Continuation message for AAHappened and other
things that happen in the LHS of “;”, e.g., Success. This results at some point
in 2 “World” instances as children of “;”.
I would think that the old behaviour was “better”; at least it looks nicer.

Could you find out what has changed exactly and why?
It may be nice to revert to the old way of handling,
in case the change had not been made to resolve a problem.
