Do we need so many whitespace?

code-whitespaces.php

<?php

public function page_title( string $title ): string {
    $endpoint_title = $this->get_endpoint_title();

    if ( $endpoint_title && false === strpos( $title, $endpoint_title ) ) {
        $title = $endpoint_title;

        remove_filter( 'single_post_title', [ $this, 'page_title' ] );
    }

    return $title;
}
