Windicss intellisense doesn't allow custom patterns

[numfin]

From source code:

    Object.entries(config).map(([key, value]) => {
      if (typeof value === 'string') {
        fileTypes[key] = { type: value in patterns ? value : 'css' };
      } else {
        const pattern = (value.patterns === undefined || value.patterns.length === 0) ? undefined : value.patterns;
        if (key in fileTypes) {
          fileTypes[key] = { type: value.type || fileTypes[key].type, pattern: fileTypes[key].pattern ? pattern ? connect([(fileTypes[key].pattern as RegExp).source, ...pattern]) : fileTypes[key].pattern : pattern ? connect([...pattern]) : undefined };
        } else if (value.type && value.type in fileTypes) {
          fileTypes[key] = {
            type: value.type || fileTypes[value.type].type,
            pattern: fileTypes[value.type].pattern ? pattern ? connect([(fileTypes[value.type].pattern as RegExp).source, ...pattern]) : fileTypes[value.type].pattern : pattern ? connect([...pattern]) : undefined };
        }
      }
    });

Here basically 3 conditions:

• If includeLanguages.[language] exists in your pattern collection (html,js,css) we use predefined pattern
• If includeLanguages.[language] exists in your fileType collection - we still using predefined pattern
• If includeLanguages.[language].type in your fileType collection - we use predefined collection.

Why i cannot just use my own pattern without predefined one (omit type field)?
