EntityAccessControlHandler::checkEntityOwnerPermissions() doesn't cache update/delete results per user

  if ($account->id() == $entity->getOwnerId()) {
        $permissions = [
          "$operation own {$entity->getEntityTypeId()}",
          "$operation any {$entity->getEntityTypeId()}",
          "$operation own {$entity->bundle()} {$entity->getEntityTypeId()}",
          "$operation any {$entity->bundle()} {$entity->getEntityTypeId()}",
        ];
      }
      else {
        $permissions = [
          "$operation any {$entity->getEntityTypeId()}",
          "$operation any {$entity->bundle()} {$entity->getEntityTypeId()}",
        ];
      }

      $result = AccessResult::allowedIfHasPermissions($account, $permissions, 'OR');

Looks like a pure omission. This code checks the owner ID, but doesn't add ->cachePerUser() to the result, even though it must.
