Large Integers will fail integer validation test

I believe this issue was introduced by this issue: https://www.drupal.org/node/2857854
And this commit: https://cgit.drupalcode.org/webform/commit/?h=7.x-4.x&id=be55cd4d6209d49...

The specific code affecting my immediate problem is from number.inc line 659:

// Integer test.
if ($element['#integer'] && filter_var((float) $numeric_value, FILTER_VALIDATE_INT) === FALSE) {
  form_error($element, t('!name field value of @value must be an integer.', array('!name' => $element['#title'], '@value' => $value)));
}

It appears to me that $numberic_value is cast to (float) and then validated as an int which will always === FALSE.
That makes the conditional TRUE, and we will always get a form error.

As a result, we can not submit a form that includes a number field that requires an integer.

$numeric_value is "standardized" and verified as numeric further up the parent conditional (lines 634, 635), so I feel like casting this as a float is unnecessary, even given the arguments in the previous issue for the other instances of this change.

I will attach a patch removing the cast to float on 659 in order to solve our use case, and will circle back to review the other cases if discussion here warrants it.
