Because when you close one stack, another stack has to become the new
topStack and it is resumed. If you check "the target" in your
resumeStack handler, you will be able to see which stack is getting
the resumeStack message.

Yes, every part of the IDE is a stack. But nearly all the IDE stacks
have names starting with "rev", so in your tools, you could check "the
short name of the target" and if it starts with "rev", just pass the
message.
