Reject in ansible list variable

I have such a variable:

apps:
 - {name: kapitalism, extension: .war}
 - {name: socialism, extension: .war}
 - {name: somethingelse, extension: .ear}

And I need to make another one based on it, which will not include some of the list. I'm trying this:

- name: Reject this please
  set_fact:
    apps: "{{ apps | map(attribute='name') | reject('search',item.name) | list }}"
  when: "item.name.find('socialism') != -1"
  with_items: "{{ apps }}"

But here I get such a problem that the extension parameter is lost and I get the variable:

apps: [u'kapitalism', u'somethingelse']

How to make a variable like this:

apps:
 - {name: kapitalism, extension: .war}
 - {name: somethingelse, extension: .ear}

?

The play below

    - hosts: localhost
      vars:
        apps2: []
        apps:
          - {name: A, extension: .ab}
          - {name: B, extension: .ab}
          - {name: C, extension: .c}
    
      tasks:
        - set_fact:
            apps2: "{{ apps2 + [ item ] }}"
          loop: "{{ apps }}"
          when: item.name != 'C'
        - debug:
            var: apps2

gives (abridged):

    "apps2": [
        {
            "extension": ".ab", 
            "name": "A"
        }, 
        {
            "extension": ".ab", 
            "name": "B"
        }
    ]

The same result can be achieved by rejectattr

    - set_fact:
        apps2: "{{ apps|rejectattr('name', 'match', 'C')|list  }}"
