There is a wrong assumtion that types are same.

Minimal PHP Code Causing Issue

See https://getrector.com/demo/686d0b75-53c4-490a-9730-d1a21ffe1b78

<?php

final class DemoFile
{
     public function run(int|string|float $firstValue, int|string|float $secondValue)
     {
         return $firstValue == $secondValue;
     }
     
     public function rector(int|string|float $firstValue, int|string|float $secondValue)
     {
         return $firstValue === $secondValue;
     }
}

$demo = new DemoFile();
var_dump($demo->run('0', 0) === $demo->rector('0', 0)); #false
