Details

When I integrate rslint at bytedance/UI-TARS-desktop#1144 ,⚡ It's fast! but encountered an unexpected leftover whitespace that should have been removed.

Source Code:

  if (!isZodSchema(schema)) {
    return schema as JSONSchema;
  }

Formatted Result

  if (!isZodSchema(schema)) {
    return schema  ;
  }

Expected Result

  if (!isZodSchema(schema)) {
    return schema;
  }
