Flags or (something else) increase the number of reactions

I have the impression that flags on a post increase the number of reactions. For example on ‘Preinstalled’ plugin label on hosted sites - #2 by Moin I see

I also noticed posts where the difference was even greater: for example Custom user menu tab

And on my forum after I reacted with on a flagged post I see

I checked the json of my first example:

        "reactions": [
          {
            "id": "heart",
            "type": "emoji",
            "count": 5
          }
        ],
        "current_user_reaction": null,
        "reaction_users_count": 4,

So I think the count which is calculated here causes this issue:

            # Reactions using main_reaction_id only have a `PostAction` record,
            # not any `ReactionUser` records, as long as the main_reaction_id was never
            # changed -- if it was then we could have a ReactionUser as well.
            reaction_likes, reactions =
              reactions.partition { |r| r[:id] == DiscourseReactions::Reaction.main_reaction_id }
          
            reactions << {
              id: DiscourseReactions::Reaction.main_reaction_id,
              type: :emoji,
              count: likes.size + reaction_likes.sum { |r| r[:count] },
            }
          
            reactions.sort_by { |reaction| [-reaction[:count].to_i, reaction[:id]] }
          end
          
          add_to_serializer(:post, :current_user_reaction) do
            return nil if scope.is_anonymous?
          
            object.emoji_reactions.each do |reaction|
              reaction_user = reaction.reaction_users.find { |ru| ru.user_id == scope.user.id }
