Token and recursive error

Hello,

When we are on the admin/config/search/metatag/... page, in the token window, there are meta values available.

If we use it like [current-page:metatag:description] , when we display a front office page, we have an error message because of a loop.

"The website encountered an unexpected error. Please try again later.
Error: Xdebug has detected a possible infinite loop, and aborted your script with a stack depth of '256' frames in is_array() (line 31 of core\lib\Drupal\Component\Assertion\Inspector.php)."

I suggest you to check if they are used to alert user because I search an half day why I had this error message...

Thank you
