7.3.0

Description

It appears that default values don't work with the ObjectMapper.

OptionsResolver has a method to ignore missing properties, but it seems like it shouldn't need a way to ignore properties if they have a default value.

How to reproduce

        $mapper = new ObjectMapper();
        $target = 'App\Dto\MyClass';
        $obj = (object) ['id'=>'abc'];
        $entity = $mapper->map($obj, $target);

<?php

namespace App\Dto\;

class MyClass
{
    public function __construct(
        public string  $id,

        #[Map(source: 'optional', if: 'isset')]
        public ?string $optional = null,
    {

    }
}
