Bug description:Possible array indicies regression

Description:
------------
It looks like there are some weird behavior with array indices. If you
look at https://3v4l.org/IOvBR the output is is different for
PHP 7.2+
(and also for HHVM 3.21+). After looking deeper at what may be wrong I
ended to write https://3v4l.org/gG7BG which gives the same
output for
any PHP version. It looks like calling unset() on one array element and
then appending an item to this array produce a different result in PHP
7.2+.
