Comment (by desrosj):

 #43583 will introduce an `is_countable()` polyfill for the PHP 7.3
 function with the same name. I think it makes sense to start using that
 function here to fix this warning.

 [attachment:43374.patch] utilizes the `is_countable()` function to avoid
 the PHP warning. Of course, this depends on the patch in #43583 being
 committed first.
