Post Preview Link Not Filtering As Draft

[TeamDNK]

Description
We are currently using preview_post_link to customize the preview link for a custom post type that we have registered. The hook works well while the post is in a "publish" state but fails to apply while the post is in draft mode nor is there any hook that I can find that filters the preview link specifically while in draft mode. The filter looks similar to this:

<?php

add_filter( 'preview_post_link', array( $this, 'change_preview_link' ), 10, 2 );

public function change_preview_link( $preview_link, $post ) {
	if ( $post->post_type !== $this->post_type) return $preview_link;

	// ...Parse/construct link
	
	return $preview_link;
}

?>

The behavior I expected was for the preview button to be filtered as a draft, auto-draft, and published. I assumed that I would be specifying any unique logic using $post->post_status to assign conditionally or that there would be a hook specific to the preview link as a draft for example preview_post_link_draft. Any help would be appreciated.

Thank you,

Hi there @TeamDNK ! I'm afraid this is a known issue with no certain timeline to be fixed. You can read more about it in #13998. I'm going to go ahead and close this one as it's essentially a duplicate of #13998, but please feel free to reopen if this doesn't answer your question!
