Psalm found a new false positive on my work project with last master.

I not sure since when the issue is there, it may be related to: #4934

I found these snippets:

https://psalm.dev/r/228ce9f5ad

<?php

$xml = new SimpleXMLElement('');
$result = $xml->xpath('');
$result[0]->attributes()->id;

Psalm output (using commit 00f3ccb):

INFO: PossiblyUndefinedIntArrayOffset - 5:1 - Possibly undefined array offset 'int(0)' is risky given expected type 'array-key'. Consider using isset beforehand.

ERROR: UndefinedPropertyFetch - 5:1 - Instance property SimpleXMLIterator::$id is not defined
