Description:
------------
A generator that yields values from an array does not throw an exception when calling the rewind
method after multiple yields from same yield construction.
Can also be seen at https://3v4l.org/NZ77U
Test script:
---------------
<?php
$generator = (static function () {
yield from [1,2,3];
})();
$generator->next();
$generator->next();
$generator->rewind();
echo $generator->current(); # 3
Expected result:
----------------
RuntimeException on line $generator->rewind();
Actual result:
--------------
3
