Help page at /admin/help/token displays "1"

In token_help, there is this code:

if ($route_name == 'help.page.token') {
    $current_url = Url::fromRoute('<current>');
     if ($current_url->toString() != 'admin/help/token') {
      // Because system_modules() executes hook_help() for each module to 'test'
      // if they will return anything, but not actually display it, we want to
      // return a TRUE value if this is not actually the help page.
      return TRUE;
    }

Since my site is located at michelle.dev/d8b6, $current_url->toString() returns "/d8b6/admin/help/token" which makes it just return TRUE.

I am running the beta 6 of core but I am fairly sure I'm using the latest Token dev snapshot.
