[QUESTION] (Possibly a bug) How to apply traits to components used for GrapesJs initialization

I am using

        this.gjs.DomComponents.addType('some-name', {
            isComponent: (el: HTMLElement) => {
                let isCmp = false;
                if (el.attributes) {
                    isCmp = el.attributes['some-attribute'] !== undefined;
                }
                return isCmp;
            },
            model: {
                defaults: {
                    traits: [
                        {
                            type: 'select', // Type of the trait
                            label: 'Trait label', // The label you will see in Settings
                            name: 'some-attribute', // The name of the attribute/property to use on component
                            options: myItems.map(x => ({ id: x.id, name: x.name }))
                        }
                    ],
                    // As by default, traits are binded to attributes, so to define
                    // their initial value we can use attributes
                    attributes: { 'some-attribute': '' },
                },
            },
        });

This works but only for blocks which are added/drag-dropped to the editor manually after it is initialized. If we supply components when we call grapesjs.init({..., components: [..]}), the components defined in components do not have the traits. How can we apply traits to initially loaded components too, not only to these added later manually ?
