Unable to have a flattened object use same property name as the object above

[Sam-Mear]

See the json

{
      "field": "ur.entity_type",
      "operator": "=",
      "value": "product"
}

and the PHP classes:

class Filter
{
    public function __construct(
        #[\Crell\Serde\Attributes\Field(flatten: true)]
        public ValidatedString $field,
        public string $operator,// todo: move to enum
        public string $value,
    ) {
    }
}

class ValidatedString
{
    protected const ALLOWED_PATTERN = '/^[a-z.]+$/';

    public function __construct(
        public string $value
    ) {}

    #[\Crell\Serde\Attributes\PostLoad]
    protected function validate(): void
    {
        if (!preg_match(self::ALLOWED_PATTERN, $this->value)) {
            throw new \InvalidArgumentException(
                sprintf(
                    'Invalid text "%s". Only lowercase letters (a-z) and dots (.) are allowed.',
                    $this->value
                )
            );
        }
    }
}

Due to both these objects having the property of value It fails around here src/PropertyHandler/ObjectImporter.php::103 where you're passing in $remaining, and later on you get the error "Warning: Undefined array key "value" in /var/www/html/vendor/crell/serde/src/PropertyHandler/ObjectImporter.php on line 70"
