I actually asked the Support Ninjas about this back in April and was told that this behavior was intentional and that it has something to do with "the way OmniFocus interacts with OSX's Core Data."

This doesn't make much sense to me, but I know only the very basics about Core Data. But at least we know it's not a bug but rather a design decision. :) Consequently, I don't expect it to change anytime soon.
