Remove all messages, when untrash a post

I'm trying to replace default untrash message to my own with error class. admin_notices do everything as expected, but even if I return empty messages array in bulk_post_updated_messages filter, I'm still see notice, but with empty content with Edit link.

According to wp-admin/edit.php, messages generating based on $bulk_counts, but bulk_post_updated_messages filter returns $bulk_messages only and even if I change this array, nothing happened. How to access $bulk_counts?

$bulk_messages = apply_filters( 'bulk_post_updated_messages', $bulk_messages, $bulk_counts );
$bulk_counts   = array_filter( $bulk_counts );

...

// If we have a bulk message to issue:
$messages = array();
foreach ( $bulk_counts as $message = $count ) {
    if ( isset( $bulk_messages[ $post_type ][ $message ] ) ) {
        $messages[] = sprintf( $bulk_messages[ $post_type ][ $message ], number_format_i18n( $count ) );
    } elseif ( isset( $bulk_messages['post'][ $message ] ) ) {
        $messages[] = sprintf( $bulk_messages['post'][ $message ], number_format_i18n( $count ) );
    }

    if ( 'trashed' === $message  isset( $_REQUEST['ids'] ) ) {
        $ids        = preg_replace( '/[^0-9,]/', '', $_REQUEST['ids'] );
        $messages[] = 'a href=' . esc_url( wp_nonce_url( edit.php?post_type=$post_typedoaction=undoaction=untrashids=$ids, 'bulk-posts' ) ) . '' . __( 'Undo' ) . '/a';
    }

    if ( 'untrashed' === $message  isset( $_REQUEST['ids'] ) ) {
        $ids = explode( ',', $_REQUEST['ids'] );

        if ( 1 === count( $ids )  current_user_can( 'edit_post', $ids[0] ) ) {
            $messages[] = sprintf(
                'a href=%1$s%2$s/a',
                esc_url( get_edit_post_link( $ids[0] ) ),
                esc_html( get_post_type_object( get_post_type( $ids[0] ) )-labels-edit_item )
            );
        }
    }
}

As stated before, bulk messages output based on $bulk_counts variable and can't be edited in admin_notices hook. This is strange, because they has their own html wrapping in wp-admin/edit.php without any actions and filters. So I dig deeper in WP core.

$bulk_counts variable generating in the wp-admin/edit.php in this line:

$bulk_counts = array(
    'updated'   => isset( $_REQUEST['updated'] ) ? absint( $_REQUEST['updated'] ) : 0,
    'locked'    => isset( $_REQUEST['locked'] ) ? absint( $_REQUEST['locked'] ) : 0,
    'deleted'   => isset( $_REQUEST['deleted'] ) ? absint( $_REQUEST['deleted'] ) : 0,
    'trashed'   => isset( $_REQUEST['trashed'] ) ? absint( $_REQUEST['trashed'] ) : 0,
    'untrashed' => isset( $_REQUEST['untrashed'] ) ? absint( $_REQUEST['untrashed'] ) : 0,
);

As we can see, untrashed key gets from the query string. If we untrash single record, this action processing in wp-admin/post.php in this code:

case 'untrash':
        check_admin_referer( 'untrash-post_' . $post_id );

        if ( ! $post ) {
            wp_die( __( 'The item you are trying to restore from the Trash no longer exists.' ) );
        }

        if ( ! $post_type_object ) {
            wp_die( __( 'Invalid post type.' ) );
        }

        if ( ! current_user_can( 'delete_post', $post_id ) ) {
            wp_die( __( 'Sorry, you are not allowed to restore this item from the Trash.' ) );
        }

        if ( ! wp_untrash_post( $post_id ) ) {
            wp_die( __( 'Error in restoring the item from Trash.' ) );
        }

        $sendback = add_query_arg(
            array(
                'untrashed' => 1,
                'ids'       => $post_id,
            ),
            $sendback
        );
        wp_redirect( $sendback );
        exit;

no filters and actions again, but at the end we got wp_redirect() function, which has a filter wp_redirect.

To disable messages, we must remove untrashed=1 argument and optional ids=*** with current post id. In my case I'm writing a flag in session and check this flag in wp_redirect

After redirection

'untrashed' => isset( $_REQUEST['untrashed'] ) ? absint( $_REQUEST['untrashed'] ) : 0;

part returns 0 and according to code in my initial post messages will disappear.

At this time this is the only solution which I've found. Any other solutions are welcomes.
