Snippet doesn’t accept multi-line comment like /* … */

Hello,

I was testing and debugging a snippet for generateblocks query loop. And when I put one part of the code in comment like below, site crashed.

    /* comment
    comment
    comment
    comment */

Error log

PHP Parse error:  Unmatched '}' in /.../wp-content/wpmastertoolkit/code-snippets/include-1755.php on line 5

Tested snippet

add_filter( 'generateblocks_query_loop_args', 'snip3w_gb_query_orderby_members', 10, 2 );

function snip3w_gb_query_orderby_members( $query_args, $attributes ) { 
    if ( ! is_admin() && 
        ! empty( $attributes['className'] ) 
        && strpos( $attributes['className'], 'query-orderby-members' ) !== false 
    ) { 
        $query_args['orderby'] = 'title'; 
        $query_args['order'] = 'DESC'; 

        /*$query_args = array_merge( 
            $query_args, array( 
                'orderby' => array( 
                    'menu_order' => 'ASC', 
                    'title' => 'ASC', 
                 ) 
             )
        );*/ 
    } 

    return $query_args; 
}
