Attached Images in First Comment Are Not Rendered / Published

Steps to reproduce

1. Open the post composer in Mixpost and select a supported social account (e.g., LinkedIn, Facebook, Instagram).
2. Enable the First Comment option.
3. Attach/upload an image (e.g., PNG/JPEG) to the First Comment section.
4. Schedule or immediately publish the post.
5. Check the published post and its first comment directly on the target social platform.

Expected behavior

The first comment should be published along with the attached image, displaying the media correctly in the comment thread.

Actual behavior

The first comment is either published without the attached image (text-only) or the image fails to render entirely on the social platform.

Please check whether this issue occurs across all supported platforms (LinkedIn, Facebook, Instagram)
