Bug: CDN S3 Sync

We have many such filters as follows that classify files into their own unique directories based on filename patterns.

add_filter('wp_handle_upload_prefilter', 'icons_upload_filter' );

function icons_upload_filter( $file ){
		$is_icon = stripos($file['name'], 'icon-');
		if( $is_icon !== false ){
			add_filter('upload_dir', 'icons_post_upload_dir');
		}

    return $file;
}

function icons_post_upload_dir($path){
	$custom_dir = '/icons';
	$path['path']    = str_replace($path['subdir'], '', $path['path']); //remove default subdir (year/month)
	$path['url']     = str_replace($path['subdir'], '', $path['url']);
	$path['subdir']  = $custom_dir;
	$path['path']   .= $custom_dir;
	$path['url']    .= $custom_dir;
	return $path;
}

The issue is that when W3TC tries to sync files to S3 it uses the wrong path and we end up seeing the following error.
wp-content/uploads/icon-ad1.png Source file not found.

But when I check the path of the file in wp_posts or wp_postmeta we see the corrent URL.

Is there a filter in W3TC we can use to correct the path while uploading to S3?
