Media modal in post edit context thumbnail

After replacing an image, the old image is still being displayed in the media modal, in the context of the edit post screen, when replacing an image in an existing image block.
The image thumbnails are of the new image but the main thumbnail is still the old one.

This code busts the cache partially it seems

```
add_action( 'replace_files.merge_replacement.replaced', function ( $post_id ) {
// Purge the server's cache.
\Altis\Cloud\Cloudfront_Media_Purge\purge_media_file_cache( $post_id );
});
```

It does eventually load the new image, I tried again after a few hours
