Nested attributes doesn't run removing association callbacks

class Person < ActiveRecord::Base
   has_many :emails, :after_remove => :set_preferred_email

   accepts_nested_attributes_for :emails, :allow_destroy => true

   private
     def set_preferred_email
       # ...
     end
end

person.emails.delete(email) # => it run the callback

person.update_attributes :emails_attributes => [{:id => email.id, :_delete => 1}] # => it doesn't run the callback

I created a patch and a LH ticket: http://bit.ly/JjgfZ
