Description:
------------
See the code below. It should print 'default value', but when I'll create property $obj->{1}, it prints 'new value'.

This affects PHP >= 7.2 https://3v4l.org/S5tJV and objects where property key is integer.

Test script:
---------------
<?php

class Test
{
	public $prop = 'default value';
}

$obj = new Test;
// $obj->{1} = null;

$arr = (array) $obj;
$arr['prop'] = 'new value';

echo $obj->prop;
