plugin-form-builder: Type error when adding fields to existing blocks

[blobmold]

I am encountering a type error whenever I am trying to extend existing blocks.

import { fields } from '@payloadcms/plugin-form-builder';

formBuilder({
    fields: {
        select: {
            ...fields.select,
            fields: [
                ...fields.select.fields,
                {
                    name: 'hasMultiple',
                    label: 'Has Multiple',
                    type: 'checkbox',
                    defaultValue: false,
                },
            ],
        },
    },
}),

This is the error I am getting: Property 'fields' does not exist on type 'Block | ((fieldConfig?: boolean | FieldConfig) => Block)'. Property 'fields' does not exist on type '(fieldConfig?: boolean | FieldConfig) => Block'.ts(2339)

it will work if you do a casting of the field as Block (fields.select as Block)

select: {
            ...fields.select,
            fields: [
                ...(fields.select as Block).fields,
                {
                    name: 'hasMultiple',
                    label: 'Has Multiple',
                    type: 'checkbox',
                    defaultValue: false,
                },
            ],
        },
