I’ve created a workaround class, which can be copied into functions.php:

class Bypass404Redirect {
	function __construct(){
		add_action('template_redirect', array($this, 'strip'), 9);
		add_action('template_redirect', array($this, 'restore'), 11);
	}
	private $uri = '';

	function strip(){
		$this->uri = $_SERVER['REQUEST_URI'];
		$_SERVER['REQUEST_URI'] = preg_replace('/\?.*/', '', $_SERVER['REQUEST_URI']);
	}

	function restore(){
		$_SERVER['REQUEST_URI'] = $this->uri;
	}
}
new Bypass404Redirect();
