This is definitely a bug.
I tried to write a bug report but have no success.
https://bugs.php.net/bug.php?id=74255

This is a minimal implementation:
<?php
session_module_name('files');
ini_set('session.use_strict_mode', '1');

session_set_save_handler(new MySessionHandler(), true);

session_start();
var_dump(session_id());

class MySessionHandler extends SessionHandler
{
     /**
      * Getting full path to session file
      *
      * It's depend on internal realization of 'files' hander.
      * Must be reviewed after each php release.
      */
     private function getFullPathName(string $key) : string
     {
         if (empty($filename = session_save_path())) {
             $filename = sys_get_temp_dir();
         } elseif (strpos($filename, ';') !== false) {
             $data = explode(';', $filename);
             $count = $data[0];
             $filename = end($data);
             for ($i = 0; $i < $count; $i++) {
                 $filename .= '/' . $key[$i];
             }
         }
         return $filename.'/sess_'.$key;
     }

     public function validateId($key)
     {
         return file_exists($this->getFullPathName($key));
     }
}
