 Status: Accepted => Rejected

While the particular implementation of the event handler registry in zope.component allows for some predictability, this should be considered an implementation detail. Officially, one should not depend on the execution order of event handlers. I'm rejecting this issue therefore since there's no bug.

Follow-up to #2298.

Handlers for sublocations are sometimes called top-down, other times bottom-up. I have not yet found out why.

Apparently, ObjectEvents registered for IItem are top-down while ObjectEvents registered for custom interfaces are bottom-up.

I'll have tests ready as time allows.
