Wrong implicit integer key inferred in static arrays

Expected: key for the "aa" element should be inferred to be 6 (https://3v4l.org/TYqhH)
Actual: it's inferred to be 2

I found these snippets:

<?php
class C {
    const A = [5 => "a", "zz" => "z", "aa"];
}
$arr = C::A;
/** @psalm-trace $arr */;

Psalm output (using commit 7c339c1):

INFO: Trace - 6:25 - $arr: array{2: "aa", 5: "a", zz: "z"}

INFO: UnusedVariable - 5:1 - $arr is never referenced or the value is not used
