Mongoid unscoped model causing other model to be unscoped

Question

I'm using default scopes in Mongoid, and have seen some odd behavior.

I have two models in question, call them Category and Item. Item belongs_to Category, although in testing, this seems to not matter. Both models have a status field (with different names), and I have a default scope on both models related to this status field.

When I pass a block to Category.unscoped, it removes the default scope from Item, as well. Here's what an example callsite looks like:

Category.unscoped do
  # these are equal, when I do not want them to be
  Item.count == Item.unscoped.count

  # these are unequal, even though I want them to be the same
  Item.count != Item.where({status: {"$ne" => "trash"}}).count
end

My question is: is there a way to use default scopes which will allow Category.unscoped to remove the default scope from Category, without removing default scopes from other models, such as Item?

For information this issue has been fixed in recent releases of mongoid:

without_default_scope suppresses default scopes of other models
