Wrong type generation using sanity typegen

[Kuboczoch]

Describe the bug

The typegen is returning the wrong type

To Reproduce

Steps to reproduce the behavior:

1. This is my query:

Groq query

const howToTestPageQuery = groq`*[_type == "testingPage" && (language == $regionLanguage || language == $language || language == '${DEFAULT_LANGUAGE}') && !(_id match 'drafts*')]{
  ${SORT_ORDER},
  hero{
    ${HERO} 
  },
  modules[]{
    _key,
    _type,
    _type == "informationSection" => {
      title,
      cards     
    },
    _type == "featureSection" => {
      title,
      subtitle,
      features     
    },
    _type == "video" => {
      url,
      type,
      preview,
      meta,
      filename,
      id
    },
    _type == "resultSection" => {
      title,
      subtitle, 
      imageMobile, 
      imageDesktop,
      button
    },
  },
  ${SEO},
} | order(sortOrder desc)[0]
`;

2. It produces this type:

Generated type using `sanity typegen generate`

export type TestingPage = {
_id: string;
_type: 'testingPage';
_createdAt: string;
_updatedAt: string;
_rev: string;
store?: ManualSlug;
seo?: SeoPage;
hero?: Banner;
modules?: Array<
  | {
      title?: string;
      cards?: Array<{
        title?: string;
        text?: string;
        _key: string;
      }>;
      _type: 'informationSection';
      _key: string;
    }
  | {
      title?: string;
      subtitle?: string;
      features?: Array<
        {
          _key: string;
        } & Feature
      >;
      _type: 'featureSection';
      _key: string;
    }
  | {
      title?: string;
      subtitle?: string;
      button?: Link;
      imageDesktop?: ShopifyAsset;
      imageMobile?: ShopifyAsset;
      _type: 'resultSection';
      _key: string;
    }
  | ({
      _key: string;
    } & ShopifyAsset)
>;
language?: string;
};

// Not part of this particular query but required to get the context
export type ShopifyAsset = {
_type: 'shopify.asset';
filename?: string;
id?: string;
meta?: ShopifyAssetMetadata;
preview?: ShopifyAssetPreview;
type?: string;
url?: string;
};

3. My module of `_type` `video` is generated using the wrong type of the `ShopifyAsset` `shopify.asset`.

Expected behavior

The module should been of a _type video.
So instead of:

      | ({
        _key: string;
      } & ShopifyAsset)

I want to get the following:

      | ({
        _key: string;
        _type: 'video'
      } & Omit<ShopifyAsset, '_type'>)
