Custom product status get filtered on all product list views

I think Below code will slove your problem.I have tested it.

/**
* Add 'Unread' post status.
*/
function wpdocs_custom_post_status(){
register_post_status( 'unread', array(
'label' => _x( 'Unread', 'post' ),
'label_count' => _n_noop( 'Unread (%s)', 'Unread (%s)'),
'public' => true,
'exclude_from_search' => false,
'show_in_admin_all_list' => true,
'show_in_admin_status_list' => true
));
}
add_action( 'init', 'wpdocs_custom_post_status' );
function my_custom_status_add_in_quick_edit() {
echo "
jQuery(document).ready( function() {
jQuery( 'select[name=\"_status\"]' ).append( 'Unread' );
});
";
}
add_action('admin_footer-edit.php','my_custom_status_add_in_quick_edit');
function my_custom_status_add_in_post_page() {
echo "
jQuery(document).ready( function() {
jQuery( 'select[name=\"post_status\"]' ).append( 'Unread' );
});
";
}
add_action('admin_footer-post.php', 'my_custom_status_add_in_post_page');
add_action('admin_footer-post-new.php', 'my_custom_status_add_in_post_page');
