Odd type error

[designermonkey]

Describe the bug

When I use the code below, intelephense tells me that the $clone variable is Expected type 'object'. Found 'string'. intelephense(1006).

I don't understand how that can be the case unless I've missed something obvious.

To Reproduce

    public function withFields(Fields $fields): self
    {
        $reflection = new ReflectionClass(static::class);
        $scope = $reflection->getProperty('fields')->getDeclaringClass()->getName();
        $clone = $reflection->newInstanceWithoutConstructor();

        if (self::class === $scope) {
            $clone->fields = $fields;
        }

        return $this;
    }

Expected behavior

That there is no error.
